Georges Julien Giraud (22 July – 16 March ) was a French mathematician, working in potential theory, partial differential equations, singular integrals and singular integral equations: he is mainly known for his solution of the regular oblique derivative problem and also for his extension to n –dimensional (n ≥ 2) singular integral equations of the concept of symbol of a singular integral, Doctoral advisor: Charles Émile Picard. The oblique derivative problem II Bengt Winzell* O. Introduction Let f2 be a bounded domain in R n, n=>3, of class C ~+~ and consider a unit vector field 1 on the boundary 0f2. We will consider the following boundary value problem for the second order elliptic operator 5e in f2: Find a solution of 5fu=g.

Other problems for elliptic semi-linear equations were considered by Veron et al., see e.g. [2, 12, 28]. The oblique derivative problem plays a major role in the study of re ected shocks in transonic ow [9]. Another important application of this theory is the capillary problem (see e.g. [14]). In geodesy, the most fundamental problems of the File Size: KB. Summary This book gives an up-to-date exposition on the theory of oblique derivative problems for elliptic equations. The modern analysis of shock reflection was made possible by the theory of oblique derivative problems developed by the author.

Solving an equation like this on an interval t2[0;T] would mean nding a functoin t7!u(t) 2R with the property that uand its derivatives intertwine in such a way that this equation is true for all values of t2[0;T]. The problem can be enlarged by replacing the real-valued uby a vector-valued one u(t) = (u 1(t);u 2.

The Oblique Derivative Problem of Potential Theory (Monographs The oblique derivative problem of potential theory book Contemporary Mathematics) Softcover reprint of the original 1st ed. Edition by A.T. Yanushauakas (Author)Format: Paperback.

Overview. An important part of the theory of partial differential equations is the theory of boundary problems for elliptic equations and systems of equations. Among such problems those of greatest interest are the so-called non-Fredholm boundary prob lems, whose investigation reduces, as a rule, to the study of singular integral equa tions, where the Fredholm alternative is violated for these problems.

oblique derivative problem when the vector field of the problem is tangent to the boundary of a domain on some subset. This is a typical degenerate elliptic boundary problem. The Dirichlet problem for an elliptic operator was solved in Chapter 9 by morphing a solution of the Dirichlet problem for the Laplacian on a ball into a solution of the Dirichlet problem for an elliptic operator on a ball.

In applying the method of continuity, it was necessary to show that an elliptic operator with a suitably restricted domain and range is a bounded : Lester L. Helms. facing. This is a physically motivated description of the oblique derivative problem, now we will give a mathematical one.

The Oblique Derivative Problem of Potential Theory. We establish optimal uniform estimates in the maximum norm, for solutions of Poisson's equation, with right hand side in Lebesgue spaces, under mixed Dirichlet-oblique derivative boundary conditions, where the oblique vector is required to remain uniformly transverse, and the estimates depend only on the transversality constant, but not on the regularity of the oblique by: 6.

Potential theory concerns itself primarily with the study of harmonic functions — their existence, uniqueness, and structure under various conditions. The book concludes with constructing solutions of more general elliptic equations beyond the Laplacian and discusses the oblique derivative problem, a generalization of the Neumann problem.Oblique derivative problems Gary M.
