Pharmacokinetics and Pharmacodynamics Models of Tumor Growth and Anticancer Effects in Discrete Time
Computational and Mathematical Biophysics, 2020 We study the h-discrete and h-discrete fractional representation of a pharmacokinetics-pharmacodynamics (PK-PD) model describing tumor growth and anticancer effects in continuous time considering a time scale h0, where h > 0.

Homoclinic solutions of 2nth-order difference equations containing both advance and retardation
Open Mathematics, 2016 By using the critical point method, some new criteria are obtained for the existence and multiplicity of homoclinic solutions to a 2nth-order nonlinear difference equation.

A New Algorithm for Solving Terminal Value Problems of q‐Difference Equations
Discrete Dynamics in Nature and Society, Volume 2018, Issue 1, 2018., 2018 We propose a new algorithm for solving the terminal value problems on a q‐difference equations. Through some transformations, the terminal value problems which contain the first‐ and second‐order delta‐derivatives have been changed into the corresponding initial value problems; then with the help of the methods developed by Liu and H.

Global attractivity in a genotype selection model
International Journal of Mathematics and Mathematical Sciences, Volume 29, Issue 9, Page 537-544, 2002., 2002 We obtain a sufficient condition for the global attractivity of the genotype selection model yn+1=yneβn(12−yn−k)/(1−yn+yneβn(12−yn−k)), n ∈ ℕ. Our results improve the results established by Grove et al. (1994) and Kocić and Ladas (1993).

Some discrete Poincaré‐type inequalities
International Journal of Mathematics and Mathematical Sciences, Volume 25, Issue 7, Page 479-488, 2001., 2001 Some discrete analogue of Poincaré‐type integral inequalities involving many functions of many independent variables are established. These in turn can serve as generators of further interesting discrete inequalities.

Discrete Dirac−Kähler Equation and its Formulation in Algebraic Form [PDF]
, 2016 A relationship between the discrete Dirac−Kähler equation and discrete analogues of some Dirac type equations in the geometric spacetime algebra is discussed. We show that a solution of the discrete Dirac−Kähler equation can be represented as the sum and

International Journal of Mathematics and Mathematical Sciences, Volume 23, Issue 4, Page 261-270, 2000., 2000 An open problem given by Kocic and Ladas in 1993 is generalized and considered. A sufficient condition is obtained for each solution to tend to the positive steady‐state solution of the systems of nonlinear Volterra difference equations of population models with diffusion and infinite delays by using the method of lower and upper solutions and monotone
