First sentence: In this chapter we state and prove two fundamental Sturm Theorems on zero sets for linear parabolic equations trying, whenever possible, to keep Sturm's original notations and calculations.
Description: "Geometric Sturmian Theory of Nonlinear Parabolic Equations and Applications focuses on geometric aspects of the intersection comparison for nonlinear models creating finite-time singularities. After introducing the original Sturm zero set results for linear parabolic equations and the basic concepts of geometric analysis, the author presents the main concepts and regularity results of the geometric intersection theory (G-theory). Here he considers the general singular equation and presents the geometric notions related to the regularity and interface propagation of solutions. In the general setting, the author describes the main aspects of the ODE-PDE duality, proves existence and nonexistence theorems, establishes uniqueness and optimal Bernstein-type estimates, and derives interface equations, including higher-order equations. The final two chapters explore some special aspects of discontinuous and continuous limit semigroups generated by singular parabolic equations." "Much of the information presented here has never before been published in book form or even in mathematics journals. This book forms a unique reference on second-order parabolic PDEs used as models for a wide range of physical problems."--BOOK JACKET.
