Printed in Singapore by Mainland Press PREFACE The international conference Acoustics, Mechanics, and the Related Topics of Mathematical Analysis (AMRTMA) was held on 18-22 June, 2002 at the Villa Clythia, CAES du CNRS, in Frbjus, France. This interdis- ciplinary meeting was in some respects a smaller-format copy of previous ISAAC conferences. AMRTMA was sponsored jointly by the Rbgion PACA (Provence Alpes CBte d’Azur), the CNRS (Centre National de la Recherche Scientifique) and ISAAC (International Society for Analysis, its Applica- tions and Computation). The objective of AMRTMA was two-fold. First, and above all, it was the occasion for friends and admirers of Robert P. Gilbert to celebrate his 70th birthday in a convivial atmosphere. Second, the conference was to Figure 1. Bob Gilbert on the boat to St. Tkopez during the AMRTMA conference provide a means for bringing together scientists from many different fields to discuss the intricacies and usefulness of applied mathematics, notably in the realm of mechanics. A group of over 60 persons, composed of scholars, scientists, engineers (some with their Spouses/companions and children) from the USA, Rance, Ger- many, Belgium, Italy, Greece, Austria, England, Sweden, Russia, Ukraine, Algeria, Tunisia and China, participated in this event. The quality of the (all half-hour) scientific communications (most of which appear in extenso V vi in this book) was high and the banquet in honor of R. Gilbert a memorable birthday celebration. As the participants were together (all lodged in the Villa Clythia, a vacation and conference facility of the CNRS) most of the time during the five days of the meeting, they had many occasions (notably during the meals, cocktails, and boat trip to St. Tropez) to socialize as well as exchange ideas and impressions. I would like to express my gratitude to the Centre National de la Recherche Scientifique, G. Berger, Directrice and E. Brun, Administrateur DkleguB, to the Conseil Wgional Provence-Alpes-C8te d’Azur, M. Hayot, Vice- PrBsident, to the International Society for Analysis, its Applications and Computation, H. Begehr, President of the Board, R.P. Gilbert, Member of the Board, and to the Laboratoire de MBcanique et d’Acoustique, M. Ritous, Directeur for their financial support and/or encouragement. The Scientific Committee members: A. Ben-Israel , Rutgers Univ., USA, A.-S. Bonnet Ben-Dhia, ENSTA, France, A. Bourgeat , Univ. St. Eti- enne, fiance, J. Buchanan, US Naval Acad., USA, C. Depollier, LAUM, fiance, R.P. Gilbert, Univ. Delaware, USA, G. Hile, Univ. Hawaii, USA, A. Jeffrey, Univ. Newcastle/Tyne, U.K., G. Maugin, LMM/CNRS/UPMC, fiance, F. Nicolosi, Univ. Catania, Italy, A. Panchenko, Penn State Univ., USA, A. Wirgin, LMA/CNRS, France, and Y. Xu, Univ. Tennessee, USA did a great job in selecting the communications and reviewing the papers for the proceedings book. The Organization Committee comprised of: G. Hile, Univ. Hawdi, USA, C. Tsogka, LMA/CNRS, France and A. Wirgin, LMA/CNRS, France acted efficiently in setting up the conference. I. Czyz, DBlCgation RBgionale du CNRS, Marseille, France provided pre- cious help on budgetary and financial issues, M. Morano, LMA/CNRS acted efficiently for the secretarial tasks, and E. Ogam, LMA/CNRS helped solve many problems connected with audiovisual presentations and informatics. My old friend R. Tanteri from Toulouse, France, made the web page that helped draw attention to the conference and A. DBlinibre LMA/CNRS, France installed this page on the LMA web site. The task of designing the logo of the conference was submitted to P. de Sentenac, Paris, France and to V. Quesnel, Rouen, fiance (whose design was finally retained). vii The success of the conference was largely due to the efforts of the kind and efficient personnel of the Villa Clythia: its Director, M. Chevalier, its Assistant Director, E. Porcu, and all the other members of the staff who made our stay an enjoyable experience. I wholeheartedly thank these many persons for their precious help. Next to last, but not least, I thank my wife Nicole and my daughter Zo6 for their encouragements and efficient help at the reception desk of the confer- ence.

In modern conditions, the interdisciplinary of comparative research requires an expansion of the framework of this approach, their orientations to results of new disciplines taking into account electronic means of the analysis and assessment of data with the prospect of moving from interdisciplinarity to transdisciplinarity. The interdisciplinarity in comparative research is studied in the works of foreign and domestic scientists.

    NOTES ON Lp AND SOBOLEV SPACES STEVE SHKOLLER 1. Lp spaces 1.1. Definitions and basic properties. Definition 1.1. Let 0 < p < 1 and let (X; M; µ) denote a measure space. If f : X ! R is a measurable function, then we define 1 Z p p kfkLp(X) := jfj dx and kfkL1(X) := ess supx2X jf(x)j : X Note that kfkLp(X) may take the value 1. Definition 1.2. The space Lp(X) is the set p L (X) = ff : X ! R j kfkLp(X) < 1g : The space Lp(X) satisfies the following vector space properties: (1) For each α 2 R, if f 2 Lp(X) then αf 2 Lp(X); (2) If f; g 2 Lp(X), then jf + gjp ≤ 2p−1(jfjp + jgjp) ; so that f + g 2 Lp(X). (3) The triangle inequality is valid if p ≥ 1. The most interesting cases are p = 1; 2; 1, while all of the Lp arise often in nonlinear estimates. Definition 1.3. The space lp, called \little Lp", will be useful when we introduce Sobolev spaces on the torus and the Fourier series. For 1 ≤ p < 1, we set ( 1 ) p 1 X p l = fxngn=1 j jxnj < 1 : n=1 1.2.

  • Layer Potentials for General Linear Elliptic Systems 1
    Electronic Journal of Differential Equations, Vol. 2017 (2017), No. 309, pp. 1{23. ISSN: 1072-6691. URL: http://ejde.math.txstate.edu or http://ejde.math.unt.edu LAYER POTENTIALS FOR GENERAL LINEAR ELLIPTIC SYSTEMS ARIEL BARTON Abstract. In this article we construct layer potentials for elliptic differential operators using the Babuˇska-Lax-Milgram theorem, without recourse to the fundamental solution; this allows layer potentials to be constructed in very general settings. We then generalize several well known properties of layer potentials for harmonic and second order equations, in particular the Green's formula, jump relations, adjoint relations, and Verchota's equivalence between well-posedness of boundary value problems and invertibility of layer potentials. 1. Introduction There is by now a very rich theory of boundary value problems for the Laplace operator, and more generally for second order divergence form operators − div Ar. The Dirichlet problem − div Aru = 0 in Ω; u = f on @Ω; kukX ≤ CkfkD and the Neumann problem − div Aru = 0 in Ω; ν · Aru = g on @Ω; kukX ≤ CkgkN are known to be well-posed for many classes of coefficients A and domains Ω, and with solutions in many spaces X and boundary data in many boundary spaces D and N. A great deal of current research consists in extending these well posedness results to more general situations, such as operators of order 2m ≥ 4 (for example, [19, 25, 45, 47, 53, 54]; see also the survey paper [22]), operators with lower order terms (for example, [24, 30, 34, 55, 62]) and operators acting on functions defined on manifolds (for example, [46, 50, 51]).

  • Large Impact Basins on Mercury: Global Distribution, Characteristics, and Modification History from MESSENGER Orbital Data Caleb I
    JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 117, E00L08, doi:10.1029/2012JE004154, 2012 Large impact basins on Mercury: Global distribution, characteristics, and modification history from MESSENGER orbital data Caleb I. Fassett,1 James W. Head,2 David M. H. Baker,2 Maria T. Zuber,3 David E. Smith,3,4 Gregory A. Neumann,4 Sean C. Solomon,5,6 Christian Klimczak,5 Robert G. Strom,7 Clark R. Chapman,8 Louise M. Prockter,9 Roger J. Phillips,8 Jürgen Oberst,10 and Frank Preusker10 Received 6 June 2012; revised 31 August 2012; accepted 5 September 2012; published 27 October 2012. [1] The formation of large impact basins (diameter D ≥ 300 km) was an important process in the early geological evolution of Mercury and influenced the planet’s topography, stratigraphy, and crustal structure. We catalog and characterize this basin population on Mercury from global observations by the MESSENGER spacecraft, and we use the new data to evaluate basins suggested on the basis of the Mariner 10 flybys. Forty-six certain or probable impact basins are recognized; a few additional basins that may have been degraded to the point of ambiguity are plausible on the basis of new data but are classified as uncertain. The spatial density of large basins (D ≥ 500 km) on Mercury is lower than that on the Moon. Morphological characteristics of basins on Mercury suggest that on average they are more degraded than lunar basins. These observations are consistent with more efficient modification, degradation, and obliteration of the largest basins on Mercury than on the Moon. This distinction may be a result of differences in the basin formation process (producing fewer rings), relaxation of topography after basin formation (subduing relief), or rates of volcanism (burying basin rings and interiors) during the period of heavy bombardment on Mercury from those on the Moon.

  • Degenerate Parabolic Initial-Boundary Value Problems*
    JOURNAL OF DIFFERENTIALEQUATIONS 31,296-312 (1979) Degenerate Parabolic Initial-Boundary Value Problems* R. E. SHOWALTER Department of Mathematics, RLM 8.100, The University of Texas, Austin, Texas 78712 Received September 22, 1977 l. INTRODUCTION We consider a class of implicit linear evolution equations of the form d d-t J[u(t) + 5flu(t) = f(t), t > O, (1.1) in Hilbert space and their realizations in function spaces as initial-boundary value problems for partial differential equations which may contain degenerate or singular coefficients. The Cauchy problem consists of solving (1.1) subject to the initial condition Jdu(0) = h. We are concerned with the case where the solution is given by an analytic semigroup; it is this sense in which the Canchy problem is parabolic. Sufficient conditions for this to be the case are given in Theorem 1; this is a refinement of previously known results [15] to the linear problem and it extends the related work [13] to the (possibly) degenerate situation under consideration. Specifically, we do not assume ~ is invertible, but only that it is symmetric and non-negative. Our primary motivation for considering the Cauchy problem for (1.1) is to show that certain classes of mixed initial-boundary value problems for partial differential equations are well-posed. Theorem 2 shows that if the operators ~/ and 5fl have additional structure which is typical of those operators arising from (possibly degenerate) parabolic problems then the evolution equation (1.1) is equivalent to a partial differential equation d d~ (Mu(t)) -}- Lu(t) -= F(t) (1.2) (obtained by restricting (1.1) to test functions) and a complementary boundary condition d d-~ (8,~u(t)) + 8zu(t) = g(t) (1.3) in an appropriate space of boundary values.
