Fundamental Theorems in Mathematics
SOME FUNDAMENTAL THEOREMS IN MATHEMATICS OLIVER KNILL Abstract. An expository hitchhikers guide to some theorems in mathematics. Criteria for the current list of 243 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 writ- ten down. Since [556] 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 num- ber 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.

Cauchy’s almost forgotten Lagrangian formulation of the Euler equation for 3D incompressible flow Uriel Frisch UNS, CNRS, OCA, Lab. Lagrange, B.P. 4229, 06304 Nice Cedex 4, France Barbara Villone INAF, Osservatorio Astrofisico di Torino, Via Osservatorio, 20, 10025 Pino Torinese, Italy (Dated: September 16, 2014) Two prized papers, one by Augustin Cauchy in 1815, presented to the French Academy and the other by Hermann Hankel in 1861, presented to G¨ottingen University, contain major discover- ies on vorticity dynamics whose impact is now quickly increasing. Cauchy found a Lagrangian formulation of 3D ideal incompressible flow in terms of three invariants that generalize to three dimensions the now well-known law of conservation of vorticity along fluid particle trajectories for two-dimensional flow. This has very recently been used to prove analyticity in time of fluid particle trajectories for 3D incompressible Euler flow and can be extended to compressible flow, in particular to cosmological dark matter. Hankel showed that Cauchy’s formulation gives a very simple Lagrangian derivation of the Helmholtz vorticity-flux invariants and, in the middle of the proof, derived an intermediate result which is the conservation of the circulation of the velocity around a closed contour moving with the fluid. This circulation theorem was to be rediscovered independently by William Thomson (Kelvin) in 1869. Cauchy’s invariants were only occasionally cited in the 19th century — besides Hankel, foremost by George Stokes and Maurice L´evy — and even less so in the 20th until they were rediscovered via Emmy Noether’s theorem in the late 1960, but reattributed to Cauchy only at the end of the 20th century by Russian scientists. -

Baggett, B.S. Fairbanks, Alaska May 2011 iii Abstract The Kronecker-Weber Theorem is a classification result from Algebraic Number Theory. Theorem (Kronecker-Weber). Every finite, abelian extension Qof is contained in a cyclo- tomic field. This result was originally proven by Leopold Kronecker in 1853. However, his proof had some gaps that were later filled by Heinrich Martin Weber in 1886 and David Hilbert in 1896. Hilbert's strategy for the proof eventually led to the creation of the field of mathematics called Class Field Theory, which is the study of finite, abelian extensions of arbitrary fields and is still an area of active research. Not only is the Kronecker-Weber Theorem surprising, its proof is truly amazing. The idea of the proof is that for a finite, Galois extension K of Q, there is a connection be tween the Galois group Gal(K/Q) and how primes of Z split in a certain subring R of K corresponding to Z in Q. -
Takagi's Class Field Theory
RIMS Kôkyûroku Bessatsu B25 (2011), 125160 Takagis Class Field Theory ‐ From where? and to where? ‐ By * Katsuya MIYAKE §1. Introduction After the publication of his doctoral thesis [T‐1903] in 1903, Teiji Takagi (1875‐ 1960) had not published any academic papers until1914 when World War I started. In the year he began his own investigation on class field theory. The reason was to stay in the front line of mathematics still after the cessation of scientific exchange between Japan and Europe owing to World War I; see [T‐1942, Appendix I Reminiscences and Perspectives, pp.195196] or the quotation below from the English translation [T‐1973, p.360] by Iyanaga. The last important scientific message he received at the time from Europe should be Fueters paper [Fu‐1914] which contained a remarkable result on Kroneckers Ju‐ gendtraum (Kroneckers dream in his young days): Kroneckers Jugendtraum The roots of an Abelian equation over an imagi‐ nary quadratic field k are contained in an extension field of k generated by the singular moduli of elliptic functions with complex multiplication in k and values of such elliptic functions at division points of their periods. (See Subsections 3.2 and 3.3 in Section 3.) K. Fueter treated Abelian extensions of k of odd degrees. Theorem 1.1 (Fueter). Every abelian extension of an imaginary quadratic num‐ ber field k with an odd degree is contained in an extension of k generated by suitable roots of unity and the singular moduli of elliptic functions with complex multiplication in k.

Dedekind had three older siblings. As an adult, he never employed the names Julius Wilhelm. He was born, lived most of his life, and died in Braunschweig (often called "Brunswick" in English). He first attended the Collegium Carolinum in 1848 before moving to the University of Göttingen in 1850. There, Dedekind studied number theory under Moritz Stern. Gauss was still teaching, although mostly at an elementary level, and Dedekind became his last student. Dedekind received his doctorate in 1852, for a thesis titled Über die Theorie der Eulerschen Integrale ("On the Theory of Eulerian integrals"). This thesis did not display the talent evident in Dedekind's subsequent publications. -

It originated in ancient Egypt and Mesopotamia four thousand years ago, and somewhat later also in ancient China and India. At that time, equations in the present sense, i.e., formal expressions based on a certain, perhaps very primitive notation, did not exist yet. The ancient arithmeticians were able to solve word problems leading to equations or their systems by means of meticulously memorized procedures, which can be nowadays aptly designated as algorithms. They have successfully tackled a number of problems, which often correspond to present-day problems of school mathematics, sometimes being much more difficult. Their methods of calculation largely correspond to our procedures used for solving equations or their systems. -
The Fundamental Theorem for Finite Abelian Groups: a Brief History and Proof
THE FUNDAMENTAL THEOREM FOR FINITE ABELIAN GROUPS: A BRIEF HISTORY AND PROOF. ANTHONY PIRO Abstract. The purpose of this project was to investigate the origins and history of Finite Abelian Group Theory. We will also provide a proof to the Fundamental Theorem of Finite Abelian Groups. The beginnings of Finite Abelian Group Theory can be traced back to the 18th century and followed through to the early 20th century. In this work, we will discuss many well-known mathematicians, such as Lagrange and Gauss, and their connections to finite abelian group theory. This work will also provide an in-depth proof to the Fundamental Theorem of Finite Abelian Groups. This theorem is a structure theorem, which provides a structure that all finite abelian groups share. The proof to the Fundamental Theorem of Finite Abelian Groups relies on four main results. Throughout the proof, we will discuss the shared structure of finite abelian groups and develop a process to attain this structure. 1. Brief History of Group Theory The development of finite abelian group theory occurred mostly over a hundred year pe- riod beginning in the late 18th century. During this time, mathematics saw a return of the axiomatic way of thinking, an increase in rigor across the field, and a greater degree of ab- straction in mathematics. Many of the early properties of groups were discovered by happen stance as they were stumbled upon during studies of di↵erent mathematical disciplines. We will discuss several mathematicians and there contributions to finite abelian group theory. It is important to note that many of the following results were not presented in a group theoretic context, but these results relate directly to finite abelian groups theory. -
