Essential enhancements in Abelian networks: Continuity and uniform strict monotonicity

The Annals of Probability, 2023
We prove that in wide generality the critical curve of the activated random walk model is a continuous function of the deactivation rate, and we provide a bound on its slope which is uniform with respect to the choice of the graph. Moreover, we derive strict monotonicity properties for the probability of a wide class of `increasing' events,extending ...

Generalization of equitable efficiency in multiobjective optimization problems by the direct sum of matrices [PDF]

Iranian Journal of Numerical Analysis and Optimization, 2023
We suggest an a priori method by introducing the concept of AP - equitable efficiency. The preferences matrix AP , which is based on the partition P of the index set of the objective functions, is given by the decision-maker.

Existence of weak solutions for elliptic Dirichlet problems with variable exponent [PDF]

Mathematica Bohemica, 2023
This paper presents several sufficient conditions for the existence of weak solutions to general nonlinear elliptic problems of the type \cases-{\rm div} a(x, u, \nn u)+b(x, u, \nn u)=0 &\text{in} \Omega, u=0 &\text{on} \partial\Omega, where $\

A Proof of the Strict Monotone 5-Step Conjecture [PDF]

Discrete & Computational Geometry, 2019
A computer search through the oriented matroid programs with dimension 5 and 10 facets shows that the maximum strictly monotone diameter is 5. Thus $Δ_{sm}(5,10)=5$. This enumeration is analogous to that of Bremner and Schewe for the non-monotone diameter of 6-polytopes with 12 facets.

On the principal eigenvalues of the degenerate elliptic systems

Electronic Journal of Qualitative Theory of Differential Equations, 2020
We study some qualitative properties for the set of principal eigenvalues of a degenerate elliptic system such as strict monotonicity with respect to the domain, local isolation and monotonicity and continuity of the principal eigenvalue with respect to ...
