An Exact Multiplicity Result For A Class Of Semilinear Equations

open access: yes, 1997
For a class of Dirichlet problems in two dimensions, generalizing the model case \Deltau + u(u \Gamma b)(c \Gamma u) = 0 in jxj ! R; u = 0 on jxj = R; Supported in part by the National Science Foundation. we show existence of a critical 0 ?

Attractors Of Some Reaction Diffusion Problems

open access: yes, 2007
. In this paper we study the existence and stability properties of certain solutions of a semilinear parabolic equation with Robin boundary conditions. We are actually interested in solutions that exhibit both boundary and internal layers.

On a Singular Limit Problem for Nonlinear Maxwell's Equations

open access: yes, 1998
: In this paper we study the following nonlinear Maxwell's equations "E t + oe(x; jEj)E = r \Theta H+F; H t +r \Theta E = 0, where oe(x; s) is a monotone graph of s. It is shown that the system has a unique weak solution.

Multivariate operational calculi for nonlocal boundary value problems for evolution equations

open access: yes, 2011
Here we propose a direct operational calculus approach to nonlocal boundary value problems for a large class of linear evolution equations with several space variables and one time variable.

Boundary-Value Problems for PDEs Arising in the Valuation of Structured Financial Products

open access: yes, 2016
We explicitly solve some mixed initial/boundary value problems for generalized Black-Scholes PDEs with financially relevant boundary conditions. As an illustration, new pricing formulas are obtained for convertible and reverse convertible bonds under ...

Non local evolution equations and phase transition problems

open access: yes, 2013
L'objet de cette thèse est d'étudier le comportement en temps long de solutions d'équations d'évolution non locales ainsi que la limite singulière d'équations et de systèmes d'équations aux dérivées partielles, où intervient un petit paramètre epsilon ...
