Maximum principle in nonlinear hyperbolic systems and its applications

Nonlinear Analysis: Theory, Methods & Applications, 1998
In this paper for quasilinear hyperbolic systems of the type \[ {\partial u_i\over\partial t}+ \lambda_i(t,x, u){\partial u_i\over\partial x}= \sum^n_{j=1} a_{ij}(t, x,u)u+ h_i(t,x,u),\quad i= 1,\dots, n\tag{1} \] estimates for the absolute value components of the solution of the system in the characteristic triangle \(\Delta_P\) through \(\max_{1\leq ...

Optimal Strong Maximum Principles for Fully Nonlinear Elliptic Equations

This paper investigates optimal strong maximum principles for fully nonlinear second-order elliptic equations. We explore the conditions under which a solution to such an equation cannot attain its maximum in the interior of a domain unless it is constant, even in the presence of degeneracy or superlinear gradient terms.
