On highly regular strongly regular graphs [PDF]

open access: yes, 2020
In this paper we unify several existing regularity conditions for graphs, including strong regularity, $k$-isoregularity, and the $t$-vertex condition. We develop an algebraic composition/decomposition theory of regularity conditions.

Regularity of Stochastic Kinetic Equations [PDF]

open access: yes, 2016
We consider regularity properties of stochastic kinetic equations with multiplicative noise and drift term which belongs to a space of mixed regularity ($L^p$-regularity in the velocity-variable and Sobolev regularity in the space-variable).

An induction theorem and nonlinear regularity models [PDF]

open access: yes, 2015
A general nonlinear regularity model for a set-valued mapping $F:X\times R_+\rightrightarrows Y$, where $X$ and $Y$ are metric spaces, is considered using special iteration procedures, going back to Banach, Schauder, Lusternik and Graves.

Lyapunov Functions for Weak Solutions of Reaction-Diffusion Equations with Discontinuous Interaction Functions and its Applications

open access: yesNonautonomous Dynamical Systems, 2015
In this paper we investigate additional regularity properties for global and trajectory attractors of all globally defined weak solutions of semi-linear parabolic differential reaction-diffusion equations with discontinuous nonlinearities, when initial ...

On Morrey and BMO regularity for gradients of weak solutions to nonlinear elliptic systems with non-differentiable coefficients

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2017
We consider weak solutions to nonlinear elliptic systems with non-differentiable coefficients which principal parts are split into linear and nonlinear ones. Assuming that the nonlinear part $g(x,u,z)$ is equipped by sub-linear growth in $z$ only for big

Polyconvex functionals and maximum principle

open access: yesMathematics in Engineering, 2023
Let us consider continuous minimizers $ u : \bar \Omega \subset \mathbb{R}^n \to \mathbb{R}^n $ of $ \mathcal{F}(v) = \int_{\Omega} [|Dv|^p \, + \, |{\rm det}\,Dv|^r] dx, $ with $ p > 1 $ and $ r > 0 $; then it is known that every ...

Judgement of paintings belonging to different tendencies in the 20th century painting [PDF]

open access: yesPsihologija, 2004
In this study Trifunović’ hypothesis that there are three objective lines in the development of modern art was psychologically evaluated. According to Trifunović, in the first line (Cézanne - cubism - neoplasticism - suprematism) the geometrization of ...

A new characterization of fuzzy ideals of semigroups and its applications

open access: yesAutomatika, 2021
In this paper, we develop a new technique for constructing fuzzy ideals of a semigroup. By using generalized Green's relations, fuzzy star ideals are constructed.
