Spectrum of an elliptic equation [PDF]

open access: possibleMathematical Notes of the Academy of Sciences of the USSR, 1970
It is shown that the spectrum for the first boundary-value problem for a second-order elliptic equation always lies in the half-plane λ0 ≤Re z, where is the leading eigenvalue to which there corresponds a nonnegative eigenfunction. Apart from λ0, there are no other points of the spectrum on the straight line Re z=λ0.

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 § 2, where we pose the problem of describing linear elliptic equations and their boundary problems in topological terms.

Elliptic equations and Steiner symmetrization

Communications on Pure and Applied Mathematics, 1996
Let \(G\) be an open bounded subset of \(\mathbb{R}^N\) and \(u\) a function defined on \(\overline G\). Then the function \(u^*(s)= \sup\{t\geq 0: \mu(t)> s\}\), where \(\mu\) is the distribution function of \(u\), is known as the decreasing rearrangement of \(u\).

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 ...
