A Century of Mathematics in America, Peter Duren Et Ai., (Eds.), Vol
Garrett Birkhoff has had a lifelong connection with Harvard mathematics. He was an infant when his father, the famous mathematician G. D. Birkhoff, joined the Harvard faculty. He has had a long academic career at Harvard: A.B. in 1932, Society of Fellows in 1933-1936, and a faculty appointmentfrom 1936 until his retirement in 1981. His research has ranged widely through alge bra, lattice theory, hydrodynamics, differential equations, scientific computing, and history of mathematics. Among his many publications are books on lattice theory and hydrodynamics, and the pioneering textbook A Survey of Modern Algebra, written jointly with S. Mac Lane. He has served as president ofSIAM and is a member of the National Academy of Sciences. Mathematics at Harvard, 1836-1944 GARRETT BIRKHOFF O. OUTLINE As my contribution to the history of mathematics in America, I decided to write a connected account of mathematical activity at Harvard from 1836 (Harvard's bicentennial) to the present day. During that time, many mathe maticians at Harvard have tried to respond constructively to the challenges and opportunities confronting them in a rapidly changing world. This essay reviews what might be called the indigenous period, lasting through World War II, during which most members of the Harvard mathe matical faculty had also studied there. Indeed, as will be explained in §§ 1-3 below, mathematical activity at Harvard was dominated by Benjamin Peirce and his students in the first half of this period. Then, from 1890 until around 1920, while our country was becoming a great power economically, basic mathematical research of high quality, mostly in traditional areas of analysis and theoretical celestial mechanics, was carried on by several faculty members. -
Quasi-Mean Value Theorems for Symmetrically Differentiable Functions
Tamsui Oxford Journal of Information and Mathematical Sciences 27(3) (2011) 279-301 Aletheia University Quasi-Mean Value Theorems for Symmetrically Differentiable Functions∗ Prasanna K. Sahooy Department of Mathematics, University of Louisville, Louisville, Kentucky 40292 USA Received September 14, 2009, Accepted October 13, 2010. Abstract In this paper, we give a survey of results related the various quasi- mean value theorems for symmetrically differentiable functions and pres- ent some new results. The symmetric derivative of a real function is discussed and it's elementary properties are pointed out. Some results leading to the quasi-Lagrange mean value theorem for the symmetrically differentiable functions are presented along with some generalizations. We also present several results concerning the quasi-Flett mean value theorem for the symmetrically differentiable functions. A new result that eliminate the boundary condition in the quasi-Flett mean theorem is also included. The quasi-Flett mean value theorem of Cauchy like is surveyed along with some related results. A new result that eliminate the boundary condition is presented related to the quasi-Flett mean value theorem of Cauchy like for the symmetrically differentiable func- tions. Further, by identifying several other new auxiliary functions, we present corresponding new quasi-mean value theorems which are variant of quasi-Lagrange mean value theorem, quasi-Flett mean value theorem, and quasi-Flett mean value theorem of Cauchy like for the symmetrically differentiable functions. Keywords and Phrases: Auxiliary function, Darboux property, Flett's mean value theorem, Lagrange mean value theorem, Lagrange mean value theorem of Cauchy like, Quasi-Flett mean value theorem, Quasi-Flett mean value theorem of Cauchy like, Quasi-Lagrange mean value theorem, Symmetric derivative. -
Qualitative Differentiation
transactions of the american mathematical society Volume 280, Number 1, November 1983 QUALITATIVEDIFFERENTIATION BY MICHAEL J. EVANS AND LEE LARSON Abstract. Qualitative dérivâtes and derivatives, as well as qualitative symmetric dérivâtes and derivatives, are studied in the paper. Analogues of several results known for ordinary dérivâtes and derivatives are obtained in the qualitative setting. 1. Introduction. The notions of qualitative limits, qualitative continuity, and qualitative derivatives were introduced by S. Marcus [13-15]. The purpose of the present paper is to examine qualitative differentiation and qualitative symmetric differentiation and, in particular, to present analogues of results known to hold for ordinary differentiation, symmetric differentiation, approximate differentiation, and approximate symmetric differentiation. Loosely speaking, qualitative differentiation and qualitative symmetric differentiation may be thought of as category analogues of approximate differentiation and approximate symmetric differentiation, where the set neglected near a point in the computation of difference quotients is of first category at the point in the former setting instead of density zero at the point as in the latter. We state our definitions in §2. In §3 we examine qualitative derivatives and dérivâtes. There we show that a qualitatively differentiable function on the real line is actually differentiable everywhere and obtain what may be viewed as qualitative analogues of the Denjoy-Young-Saks theorem [18]. In §4 we consider qualitative symmetric derivatives and dérivâtes. We show that with mild continuity restrictions on the primitive, a qualitative symmetric derivative must belong to Baire class one and actually be the symmetric derivative of a closely related function except at countably many points. A monotonicity theorem and related results are given. -

After completing the double blind peer reviewed process of the collection of papers Geyser Ma- thematicae Cassoviensis the acceptance rate was 80 %. Introduction to GMC Dear reader, you are opening a peer review publication dedicated to new trends in Košice’s ma- thematics - Geyser Mathematicae Cassoviensis (GMC) with contributions soundly based in research or scholarship. It seeks to cover the whole field of post-school mathematical education and/or research in all areas of mathematics. It aims to take a problem-oriented approach; to help formulate the problems of higher education, to consider alternative solutions and to test them. Lastly, it seeks to inform about the up to date research in Košice and Košice’s surround via research papers, review articles and/or short communications. The education reveals abilities but do not create them. Universities educate new generations that form the national elite. Well educated people become new workers and open-minded researchers. This points out to the fact that educational activities and problems have their important place in nowadays scientific discussions. A successful academic career is increasingly linked to a track record of publishing research which is able to reach a large audience. -

A New, Harder Proof That Continuous Functions with Schwarz Derivative 0 Are Lines
A New, Harder Proof That Continuous Functions With Schwarz Derivative 0 Are Lines J. Marshall Ash Abstract. The Schwarz derivative of a real-valued function of a real variable F is de…ned at the point x by F (x + h) 2F (x) + F (x h) lim : h 0 h2 ! The usual proof that a function with identically 0 Schwarz derivative must be a line depends on the fact that a continuous function on a closed interval attains a maximum. Here we give an alternate proof which avoids this dependence. 1. Introduction The Schwarz derivative is de…ned to be F (x h) 2F (x) + F (x + h) (1) DF (x) := lim : h 0 h2 ! Throughout this work, all functions denoted by capital Roman letters or by Greek letters will be real-valued functions of a real variable, and all functions denoted by lower case Roman letters will be maps from R2 to R. The above limit is sometimes called the second Riemann or second symmetric derivative. To see why it is a generalized second derivative, assume that F is twice di¤erentiable at a …xed point x. Then Peano’spowerful version of Taylor’sTheorem asserts that even though F 00 is not even assumed to exist at any point other than x; much less be continuous at x, we still must have1 h2 (2) F (x + h) = F (x) + F (x) h + F (x) + o h2 : 0 00 2 1991 Mathematics Subject Classi…cation.

FIRST DERIVATIVE As was said in the Introduction, in this chapter and the next we shall study the infinitesimal properties of functions which are defined on a subset of the real field R and take their values in a Hausdorff topological vector space E over the field R;for brevity we shall say that such a function is a vector function of a real variable. The most important case is that where E R (real-valued functions of a real variable). When E Rn, consideration of a vector function with values in E reduces to the simultaneous consideration of n finite real functions. Many of the definitions and properties stated in chapter I extend to functions which are defined on a subset of the field C of complex numbers and take their values in a topological vector space over C (vector functions of a complex variable). Some of these definitions and properties extend even to functions which are defined on a subset of an arbitrary commutative topological field K and take their values in a topological vector space over K. -

Elementary Real Analysis, 2Nd Edition (2008) Section 7.2
ClassicalRealAnalysis.com Chapter 7 DIFFERENTIATION 7.1 Introduction Calculus courses succeed in conveying an idea of what a derivative is, and the students develop many technical skills in computations of derivatives or applications of them. We shall return to the subject of derivatives but with a different objective. Now we wish to see a little deeper and to understand the basis on which that theory develops. Much of this chapter will appear to be a review of the subject of derivatives with more attention paid to the details now and less to the applications. Some of the more advanced material will be, however, completely new. We start at the beginning, at the rudiments of the theory of derivatives. 7.2 The Derivative Let f be a function defined on an interval I and let x0 and x be points of I. Consider the difference quotient determined by the points x0 and x: f(x) f(x ) − 0 , (1) x x − 0 representing the average rate of change of f on the interval with endpoints at x and x0. 396 Thomson*Bruckner*Bruckner Elementary Real Analysis, 2nd Edition (2008) Section 7.2. The Derivative ClassicalRealAnalysis.com 397 f f(x) f(x0) x0 x Figure 7.1. The chord determined by (x, f(x)) and (x0, f(x0)). In Figure 7.1 this difference quotient represents the slope of the chord (or secant line) determined by the points (x, f(x)) and (x0, f(x0)). This same picture allows a physical interpretation. If f(x) represents the distance a point moving on a straight line has moved from some fixed point in time x, then f(x) f(x ) − 0 represents the (net) distance it has moved in the time interval [x0, x], and the difference quotient (1) represents the average velocity in that time interval. -

SOME FUNDAMENTAL THEOREMS IN MATHEMATICS OLIVER KNILL Abstract. An expository hitchhikers guide to some theorems in mathematics. Criteria for the current list of 200 theorems are whether the result can be formulated elegantly, whether it is beautiful or useful and whether it could serve as a guide [6] without leading to panic. The order is not a ranking but ordered along a time-line when things were written down. Since [431] stated “a mathematical theorem only becomes beautiful if presented as a crown jewel within a context” we try sometimes to give some context. Of course, any such list of theorems is a matter of personal preferences, taste and limitations. The number of theorems is arbitrary, the initial obvious goal was 42 but that number got eventually surpassed as it is hard to stop, once started. As a compensation, there are 42 “tweetable” theorems with included proofs. More comments on the choice of the theorems is included in an epilogue. For litera- ture on general mathematics, see [158, 154, 26, 190, 204, 478, 330, 114], for history [179, 484, 304, 62, 43, 170, 306, 296, 535, 95, 477, 68, 208, 275], for popular, beautiful or elegant things [10, 406, 163, 149, 15, 518, 519, 41, 166, 155, 198, 352, 475, 240, 163, 2, 104, 121, 105, 389].
