ON ELLIPTIC EQUATIONS

Russian Mathematical Surveys, 1960
This paper, like the note on integral geometry in the last number of the "Uspekhi" , is an addendum to my paper [1]. The main idea of the paper is contained in ยง 2, where we pose the problem of describing linear elliptic equations and their boundary problems in topological terms.

Elliptic equations

2003
Abstract In this chapter we will, as usual, begin by discussing some physical situations that are modelled by elliptic equations, as defined in a rather unfocused way in Chapter 3. Most of the examples involve scalar second-order equations, several of which are special cases, such as steady states, of evolution models discussed in ...

Elliptic Equations

IBM Journal of Research and Development, 1967
A brief review is given of the literature on numerical methods for elliptic problems as reltaote tdh e ideas introduced by Courant, Friedrichs and Lewy in the fundamental paper published in Math. Ann. 100, 32 (1928). The discussion shows how the finitedifference methods have subsequently been extended and applied to higher order elliptic problems and ...
