The present paper is devoted to the behavior of the interpolating points of maximally convergent multipoint Pade approximants with fixed degree of the denominators.

In this paper we give a generalization of the classical Mellin transformation [1]. We also prove some main properties of the α‐ Mellin transform and discuss some of its applications. This paper refers to a solution of fractional differential equat

We consider a construction of finite elements (FE) which is, in some sense, dual to the construction of generalized expo‐rational B‐splines (GERBS)[1, 2]. The main result is the introduction of univariate and multivariate tensor‐product GERBS

In this work we consider Cauchy problem for the so called Gamma equation, derived by transforming the fully nonlinear Black‐Scholes equation for option price into a quasilinear parabolic equation for the second derivative (Greek) Γ = VSS of the op

A mathematical model of the system consisting of wind turbine, gear box and asynchronous generator is presented in this work. The model is linearized. Then a controller, which provides a desire mode of frequency stabilization, is developed using the

In this paper we describe a new mathematical course for engineers developed for the students in the Technical University of Sofia, the University of Civil Engineering and Geodesy and the European Polytechnical University. It is based on the computer

By means of the transmutation method we construct explicit solutions of some fractional order Volterra integral equations of second kind, with one or two different Erdelyi‐Kober operators, the latter involving hypergeometric integrals. The same met
