Non-negative and positive solutions for some indefinite sublinear elliptic problems

open access: yesBoundary Value Problems
We study the existence of non-negative and positive solutions to the indefinite sublinear elliptic problem − Δ u = λ u + m ( x ) | u | α − 1 u $\ -\Delta u=\lambda u+m(x)\left \vert u\right \vert ^{\alpha -1}u$ in Ω, u = 0 $u=0$ on ∂Ω, where Ω is a ...

The Method of Generalized Integral Guiding Function in the Periodic Problem of Differential Inclusions

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2015
In the present paper we consider new methods for solving the periodic problem for a nonlinear system governed by a differential inclusion of the following form: $$x'(t)\in F(t,x(t)).$$ In the first part of the article we assume that the multivalued map ...
