A class of nonlinear integrable PDEs admit non-smooth solitary wave solutions as certain special weak solutions. These solutions can be used to capture main attributes of solutions of these PDEs, e.g....
PRECONDITIONING A CLASS OF FOURTH ORDER PROBLEMS BY OPERATOR SPLITTING
parabolic problems fourth order problems preconditioning
2015/12/11
We develop preconditioners for systems arising from finite element discretizations of
parabolic problems which are fourth order in space. We consider boundary conditions which yield
a natural ...
Neo-Classical Minimax Problems, Thresholding, and Adaptation
Minimax Estimation Adaptive Estimation

We study the problem of estimating from data Y N(; 2
) under squared-error loss.
We de ne three new scalar minimax problems in which the risk is weighted by the size of .
Simple thresholding...
S. K. Ntouyas, Boundary Value Problems for First Order Impulsive Differential Inclusions
Boundary value problem impulsive periodic antiperiodic differential inclusions fixed point
2009/6/16
In this paper, we investigate the existence of solutions for a class of first order boundary
value problems for impulsive differential inclusions. By using suitable fixed point
theorems, we study ...
A NOTE ON SOME CAUCHY PROBLEMS WITH NONLOCAL CONDITIONS
integral solutions integrated semigroups mild solutions Cauchy Problem nonlocal conditions intermediate Banach spaces
2008/11/26
In this short note we prove the existence and uniqueness of solutions to semilinear
differential equations with nonlocal conditions in a Banach space, first in the case of a
nondensely defined opera...
