It is well known that the line of intersection of an ellipsoid and a plane is an ellipse. In this note simple formulas for the semi-axes and the center of the e
In this paper, a mathematical model is proposed to study the effect of pollutant and virus induced disease on single species animal population and its essential
In this paper we propose a numerical collocation method to approximate the solution of linear integral mixed Volterra Fredholm equations of the second kind, wit
In this paper, the vector-valued regular functions are extended to the locally convex space. The residues theory of the functions in the locally convex space is
Our aim in the present article is to introduce and study new types of retractions of closed flat Robertson-Walker W4 model. Types of the deformation retract of
