An unconditionally stable nonstandard finite difference method applied to a mathematical model of HIV infection
(De Gruyter Open, 2013)
We formulate and analyze an unconditionally stable nonstandard finite difference method for a mathematical model of HIV
transmission dynamics. The dynamics of this model are studied using the qualitative theory of dynamical ...
Multiplication of Crowns
(Instituto de Matematica de Bahia Blanca (INMABB-CONICET), 2013)
It is known that the only nite topological spaces that are H-spaces are the discrete spaces. For a nite poset which is weakly equivalent to an H-space, a generalized multiplication may be found after suitable ...
Automorphism groups of graph covers and uniform subset graphs
(Taylor and Francis Group, 2018)
Hofmeister considered the automorphism groups of antipodal graphs through the exploration of graph covers. In this note weextend the exploration of automorphism groups of distance preserving graph covers. We apply the ...
A robust spectral method for pricing of American put options on zero-coupon bonds
(Global-Science Press, 2018)
American put options on a zero-coupon bond problem is reformulated as a
linear complementarity problem of the option value and approximated by a nonlinear
partial differential equation. The equation is solved by an ...
On maximal inequalities via comparison principle
(SpringerOpen, 2015)
Under certain conditions, we prove a new class of one-sided, weighted, maximal
inequalities for a standard Brownian motion. Our method of proof is mainly based on
a comparison principle for solutions of a system of ...
Relative homotopy in relational structures
(Cambridge University Press, 2018)
The homotopy groups of a finite partially ordered set (poset) can be described entirely in the
context of posets, as shown in a paper by B. Larose and C. Tardif. In this paper we describe the relative
version of such a ...
Performance of Richardson extrapolation on some numerical methods for a singularly perturbed turning point problem whose solution has boundary layers
(KOREAN MATHEMATICAL SOC, 2014)
Investigation of the numerical solution of singularly perturbed turning point problems dates back to late 1970s. However, due to the presence of layers, not many high order schemes could be developed to solve such problems. ...
A fitted numerical method for parabolic turning point singularly perturbed problems with an interior layer
(Wiley, 2019)
The objective of this paper is to construct and analyzea fitted operator finite difference method (FOFDM) forthe family of time-dependent singularly perturbed parabolicconvection–diffusion problems. The solution to the ...
Some meta-cayley graphs on dihedral groups
(Springer, 2019)
In this paper, we define meta-Cayley graphs on dihedral groups. We fully determine the automorphism groups of the constructed graphs in question. Further, we prove that some of the graphs that we have constructed do not ...
