Minimal positive solutions for systems of semilinear elliptic equations [PDF]
Electronic Journal of Qualitative Theory of Differential Equations, 2017 The paper is devoted to a system of nonlinear PDEs containing gradient terms. Applying the approach based on Sattinger's iteration procedure we use sub and supersolutions methods to prove the existence of positive solutions with minimal growth.

Journal of Mathematical Analysis and Applications, 2011 The authors show the existence of a positive, bounded weak solution for a system of partial differential equations having a physical origin. The specific character of this system is the coupling of a variable satisfying a partial differential equation in the domain with a variable satisfying a differential equation on the boundary.

Continuity equations and ODE flows with non-smooth velocity [PDF]
, 2014 In this paper we review many aspects of the well-posedness theory for the Cauchy problem for the continuity and transport equations and for the ordinary differential equation (ODE). In this framework, we deal with velocity fields that are not smooth, but

A PIE Representation of Coupled Linear 2D PDEs and Stability Analysis using LPIs
, 2022 We introduce a Partial Integral Equation (PIE) representation of Partial Differential Equations (PDEs) in two spatial variables. PIEs are an algebraic state-space representation of infinite-dimensional systems and have been used to model 1D PDEs and time-

Positive solutions for super-sublinear indefinite problems: high multiplicity results via coincidence degree [PDF]
, 2018 We study the periodic boundary value problem associated with the second order nonlinear equation u'' + ( λa^+(t) - μa^-(t) ) g(u) = 0, where g(u) has superlinear growth at zero and sublinear growth at infinity.

Networks & Heterogeneous Media, 2010 We consider a so-called random obstacle model for the motion of a hypersurface through a field of random obstacles, driven by a constant driving field. The resulting semi-linear parabolic PDE with random coefficients does not admit a global nonnegative stationary solution, which implies that an interface that was flat originally cannot get stationary ...
