Phenotypic heterogeneity in modeling cancer evolution
Ali Mahdipour Shirayeh, Kamran Kaveh, Mohammad Kohandel +1
The unwelcome evolution of malignancy during cancer progression emerges through a selection process in a complex heterogeneous population structure. In the present work, we investi…
A new proof for the Banach-Zarecki theorem: A light on integrability and continuity
Ali Mahdipour-Shirayeh, Homayoon Eshraghi
To demonstrate more visibly the close relation between the continuity and integrability, a new proof for the Banach-Zarecki theorem is presented on the basis of the Radon-Nikodym t…
Preliminary group classification for generalized inviscid Burger's equation
A. Mahdipour-Shirayeh
Preliminary group classification for a class of generalized inviscid Burger's equations in the general form is given and additional equivalence transform…
Symmetry analysis of cylindrical Helmholtz equation
Mehdi Nadjafikhah, Ali Mahdipour-Shirayeh
In this paper, we present the point symmetry group of three-dimensional homogeneous Helmholtz equation, when we consider the cylindrical coordinate system. In continuation, we pres…
A symmetry classification for a class of (2+1)-nonlinear wave equation
Mehdi Nadjafikhah, Rohollah Bakhshandeh-Chamazkoti, Ali Mahdipour-Shirayeh
In this paper, a symmetry classification of a -nonlinear wave equation where is a smooth function on , using Lie group method, is gi…
Symmetry Analysis for a New Form of the Vortex Mode Equation
Mehdi Nadjafikhah, Ali Mahdipour--Shirayeh
Giving a new form of the vortex mode equation by a proper change of parameter, our aim is to analyze the point and contact symmetries of the new equation. Fundamental invariants an…
Multidimensional simple waves in fully relativistic fluids
T. Sahihi, H. Eshraghi, A. Mahdipour-Shirayeh
A special version of multi--dimensional simple waves given in [G. Boillat, {\it J. Math. Phys.} {\bf 11}, 1482-3 (1970)] and [G.M. Webb, R. Ratkiewicz, M. Brio and G.P. Zank, {\it…
Symmetry of Quadratic Homogeneous Differential Systems
Mehdi Nadjafikhah, Ali Mahdipour-Shirayeh
In this paper, the symmetry group of a differential system of n quadratic homogeneous first order ODEs of n variables is studied. For this purpose, we consider the action of both p…
