On the scientific work of Olga Oleinik

Abstract

The paper is a survey of scientific work of Olga Oleinik with particular regard to four arguments: 1) discontinuous solutions of hyperbolic conservation equations or systems; 2) Stefan’s phase-transitions problem; 3) partial linear differential equations with non negative characteristic form; 4) determination of classes of partial differential equations or systems, with analytic solutions.
