Extremal solutions for nonlinear neumann problems

Discussiones Mathematicae. Differential Inclusions, Control and Optimization, 2001
The authors investigate the Neumann problem in a smooth bounded domain for the equation \[ -\text{ div } \left(\|\nabla x\|^{p-2}\nabla x \right) = f(\cdot,x,\nabla x) \] with usual regularity and growth conditions on \(f\). Assuming the existence of upper and lower solutions the authors show that the set of solutions is nonvoid and directed and thus ...

INFORMATION EXTREMISM: PROBLEMS AND SOLUTIONS.

VESTNIK OF THE EAST SIBERIAN INSTITUTE OF THE MINISTRY OF INTERNAL AFFAIRS OF THE RUSSIAN FEDERATION, 2023
Введение. Статья посвящена вопросам распространения экстремистских материа-лов в сети Интернет, а именно в социальных сетях. Информационный экстремизм, как один из разновидностей экстремизма, на сегодняшний день наиболее опасен. Так как ин-формация, несущая в себе запрещенный контент, зачастую общедоступна, а распростра-нители данной информации ...

Bioenergetics and solute uptake under extreme conditions

Extremophiles, 2001
The ion and particularly the proton and sodium ion permeabilities of cytoplasmic membranes play crucial roles in the bioenergetics of microorganisms. The proton and sodium permeabilities of membranes increase with temperature. Psychrophilic and mesophilic bacteria and mesophilic, (hyper)thermophilic, and halophilic archaea are capable of adjusting the ...

DEMON Mark II: Extremal Equations Solution and Approximation

Management Science, 1968
This paper develops a new method for the solution of DEMON-type functional equations. It is shown how the latter can be reduced to solution of a separated system of simpler equations which, for discrete distributions, can be solved by linear programming methods.

Extremal Solutions of Multivalued Differential Equations

Results in Mathematics, 1988
Consider an initial value problem (1) \(u'\in F(t,u)\) a.e. on J, \(u(0)=x_ 0\) where \(J=[0,a]\subset R\), \(X=R\) n and F:J\(\times X\to 2\) \(X\setminus \phi\) is a multivalued map. Let \(K\subset R\) n be a cone and \(\leq\) the partial ordering defined by K, i.e. \(x\leq y\) iff y-x\(\in K\).

Extreme solutions of equations

1987
In the previous chapter we have encountered a number of statements S, for which the predicate transformers wlp(S,?) and wp(S,?) were given in closed form. In the next chapter we shall encounter a statement for which the predicates wlp(S,X) and wp(S,X) are given as solutions of equations of the form $${\text{Y }}:{\text{ }}\left[ {{\text{b}}.\left( {

Extremal solutions of boundary value problems

Differential Equations, 2011
To prove the existence of a solution of a two-point boundary value problem for an nth-order operator equation by the a priori estimate method, authors study extremal solutions of auxiliary boundary value problems for an nth-order differential equation with simplest right-hand side, which have a unique solution under certain restrictions on the boundary

Extremal Solutions for Semilinear Obstacle Problems

Applicable Analysis, 1996
In this paper we establish the existence of a minimum solution bounded above by an upper solution for a parabolic problem with unilateral constraint (obstacle problem). Our approach uses truncation and penalization techniques and ultimately relies on Zorn's lemma.
