A robust numerical solution to a time-fractional Black–Scholes equation
(Springer Nature, 2021)
Dividend paying European stock options are modeled using a time-fractional
Black–Scholes (tfBS) partial differential equation (PDE). The underlying fractional
stochastic dynamics explored in this work are appropriate for ...
An unconditionally stable nonstandard finite difference method to solve a mathematical model describing Visceral Leishmaniasis
(Elsevier, 2021)
In this paper, a mathematical model of Visceral Leishmaniasis is considered. The model incorporates three populations, the human, the reservoir and the vector host populations. A detailed analysis of the model is presented. ...
Codenseness and openness with respect to an interior operator
(Springer Nature, 2021)
Working in an arbitrary category endowed with a fixed (E, M) -factorization system such that M is a fixed class of monomorphisms, we first define and study a concept of codense morphisms with respect to a given categorical ...
A model of malaria population dynamics with migrants
(Mathematical Biosciences and Engineering, 2021-08)
We present a compartmental model in ordinary differential equations of malaria disease transmission, accommodating the effect of indoor residual spraying on the vector population. The model allows for influx of infected ...
Quasi-uniform structures determined by closure operators
(Elsevier, 2021)
We demonstrate a one-to-one correspondence between idempotent closure operators and the so-called saturated quasi-uniform structures on a category C. Not only this result allows to obtain a categorical counterpart P of the ...
An SEIR model with infected immigrants and recovered emigrants
(Springer Science and Business Media Deutschland GmbH, 2021)
We present a deterministic SEIR model of the said form. The population in point can be considered as consisting of a local population together with a migrant subpopulation. The migrants come into the local population for ...
Binary codes from m-ary n-cubes Q(n) (m)
(American Institute of Mathematical Sciences, 2021)
We examine the binary codes from adjacency matrices of the graph with vertices the nodes
of the m-ary n-cube Qmn
and with adjacency de ned by the Lee metric. For n = 2 and m odd,
we obtain the parameters of the code and ...
