Regularity Result for Quasilinear Elliptic Systems with Super Quadratic Natural Growth Condition

Abstract and Applied Analysis, 2013
We consider boundary regularity for weak solutions of second-order quasilinear elliptic systems under natural growth condition with super quadratic growth and obtain a general criterion for a weak solution to be regular in the neighborhood of a given ...

Natural generalization of some lattice theory concepts to partially ordered sets [PDF]

Czechoslovak Mathematical Journal, 1991
An ordered set \(P\) is Noetherian if any nonempty directed subset of \(P\) contains a greatest element. \(P\) is upper complete if any nonempty directed subset of \(P\) has a least upper bound in \(P\). Proposition 1. \(P\) is Noetherian iff it is upper complete and each of its elements is compact.

Matrix Methods for Estimating the Coherence Functions from Estimates of the Cross-Spectral Density Matrix

Shock and Vibration, 1996
It is shown that the usual method for estimating the coherence functions (ordinary, partial, and multiple) for a general multiple-input! multiple-output problem can be expressed as a modified form of Cholesky decomposition of the cross-spectral density ...

SOLUTIONS OF FRACTIONAL ORDER NONLINEAR PARTIAL DIFFERENTIAL EQUATIONS BY NATURAL DECOMPOSITION METHOD

, 2022
ADVISOR:BOKA KUMSA ( ASSOCIATE PROFESSOR) ABSTRACT . Most of nonlinear partial differential equations have many applications in physical world. However; to find the solutions of nonlinear partial differential equations are not easily solvable and hence different modified techniques were applied to get solutions of such equations.
