The Extremal Universe Exact Solution from Einstein’s Field Equation Gives the Cosmological Constant Directly [PDF]

Journal of High Energy Physics Gravitation and Cosmology
Einstein’s field equation is a highly general equation consisting of sixteen equations. However, the equation itself provides limited information about the universe unless it is solved with different boundary conditions.

Construction of Domains with All Solutions, and the Existence of Extreme Solutions

SIAM Journal on Numerical Analysis, 1981
In this paper we construct domains with all solutions of an operator equation $Fu = 0$, and prove the existence of a minimal and maximal solution. For this one requires a suitable growth condition of F and the existence of a solution of $Fu = 0$ in intervals $[\Phi ,\Psi ]$, if $\Phi $ is a subsolrution and $\Psi $ is a supersolution for $Fu = 0$.

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 ...

Approximation of extremal solution of non-Fourier moment problem and optimal control for non-homogeneous vibrating systems [PDF]

Journal of Mathematical Analysis and Applications, 2012
Trigonometric non-Fourier moment problems arise as a result of various control problem study. In current paper, the extremal solution, i.e. the one with the least L2-norm is searched for.

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 ...

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( {

On V-Extremal Solutions of the Moment Problem

Mathematical Notes, 2002
A nondecreasing function \(\sigma(u)\), \(-\infty 0\), and \(\sigma_1(u)\) and \(\sigma_2(u)\) are solutions of the same moment problem different from \(\sigma(u)\). The set of all solutions of the indeterminate moment problem (1) is described be the Nevanlinna representation: Let the class of Nevanlinna functions \(N\) supplemented with the constant \

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\(\in K\).
