Existence results for non-autonomous elliptic boundary value problems

open access: yesElectronic Journal of Differential Equations, 1994
$$-Delta u(x) = lambda f(x, u);quad x in Omega$$ $$u(x) + alpha(x) frac{partial u(x)}{partial n} = 0;quad x in partial Omega$$ where $lambda > 0$, $Omega$ is a bounded region in $Bbb{R}^N$; $N geq 1$ with smooth boundary $partial Omega$, $alpha(x) geq 0$,

Existence and multiplicity of solutions to a p-Laplacian equation with nonlinear boundary condition

open access: yesElectronic Journal of Differential Equations, 1998
We study the nonlinear elliptic boundary value problem $$ A u = f(x,u) quad { m in }Omega,,$$ $$ Bu = g(x,u) quad { m on }partial Omega,,$$ where $A$ is an operator of p-Laplacian type, $Omega$ is an unbounded domain in ${Bbb R}^N$ with non-compact ...

R-DOCO: Resilient Distributed Online Convex Optimization Against Adversarial Attacks

open access: yesMathematics
This paper addresses the problem of distributed constrained optimization in a multi-agent system where some agents may deviate from the prescribed update rules due to failures or malicious adversarial attacks.

A general law of the iterated logarithm for non-additive probabilities

open access: yesResults in Applied Mathematics
Motivated by some interesting problems in mathematical economics, quantum mechanics and finance, non-additive probabilities have been used to describe the phenomena which are generally non-additive. In this paper, we further study the law of the iterated

Nonhomogeneous quasilinear elliptic systems with small perturbations and lack of compactness

open access: yesBulletin of Mathematical Sciences
We investigate a class of quasilinear elliptic system involving a nonhomogeneous differential operator which is introduced by Stuart [Milan J. Math. 79 (2011) 327–341] and depends not only on [Formula: see text] but also on u.
