Various characterizations of finite convex geometries
are well known. This note provides similar characterizations for
possibly infinite convex geometries whose lattice of closed sets is
strongly coatomic and lower ...

This project presents a generalization of the classical logistic and the Gompertz model by using two parameter power law exponent. The suggested generalized with two parameters models was shown by numerical example to be ...

Integral equations of the first kind with a smooth kernel and perturbed right-hand side, which represents available contaminated data, arise in many applications. Discretization gives rise to linear systems of equations ...

This paper presents the results of developing a
morphological disambiguation tool for Kazakh. Starting with a
previously developed rule-based approach, we tried to cope with
the complex morphology of Kazakh by breaking ...

Representation of convex geometry as an appropriate join of compatible
orderings of the base set can be achieved, when closure operator of
convex geometry is algebraic, or finitary. This bears to the finite case proved
by ...

A lumped-parameter nonlinear spring-mass model which takes into
account the third-order elastic sti ness constant is considered for mod-
eling the free and forced axial vibrations of a graphene sheet with one

A lumped-parameter nonlinear spring-mass model which takes into account the third-order elastic
stiffness constant is considered for modeling the free and forced axial vibrations of a graphene
sheet with one fixed end ...

Recently, Einsiedler and the authors provided a bound in terms of escape of mass for the amount by which upper-semicontinuity for metric entropy fails for diagonal
ows on homogeneous spaces nG, where G is any connected ...

A novel procedure based on the Sturm’s theorem for real-valued polynomials is developed to predict and identify periodic solutions and non-periodic solutions in the pull-in analysis of a graphene-based MEMS lumped parameter ...

We prove that the Cauchy problem for a transport equation with algebraic nonlinearity of
degree p with initial data in Gevrey spaces is locally well-posed. In particular, we show that
the analyticity of solutions persists ...

(arXiv, 2018-03-19)
In the study of subdiffusive wave-packet spreading in disordered Klein-
Gordon (KG) nonlinear lattices, a central open question is whether the
motion continues to be chaotic despite decreasing densities, or tends to
become ...

Many distributions have been used as lifetime models. In this article, we propose a new three-parameter Weibull–Pareto distribution, which can produce the most important hazard rate shapes, namely, constant, increasing, ...

A unitary symplectic similarity transformation for a special class of Hamiltonian matrices to extended Hamiltonian Hessenberg form is presented. Whereas the classical Hessenberg form links to Krylov subspaces, the extended ...

We study approximations of the steady state Stokes problem governed
by the power-law model for viscous incompressible non-Newtonian flow
using the penalty formulation. We establish convergence and find error estimates.

Porous Medium Equation (PME) is one of the simplest types of of nonlinear evolution equation
of parabolic type. It emerges in the description of di erent natural phenomena, and its theory and
properties depart strongly ...

We consider the asymmetric active coupler (AAC) consisting of two coupled dissimilar waveguides with
gain and loss. We show that under generic conditions, not restricted by parity-time symmetry, there
exist finite-power, ...

We establish a criterion to decide when a countable projective limit of countable inductive limits of normed spaces is bornological. We compare the conditions occurring within our criterion with well-known abstract conditions ...
