Global functional calculus for operators on compact Lie groups [PDF]

, 2014
In this paper we develop the functional calculus for elliptic operators on compact Lie groups without the assumption that the operator is a classical pseudo-differential operator. Consequently, we provide a symbolic descriptions of complex powers of such

A direct method for solving fractional order variational problems by hat basis functions

Ain Shams Engineering Journal, 2018
This paper presents a numerical technique for solving a class of fractional variational problems using a direct method based on operational matrix of generalized hat basis function. The fractional derivative is defined in the Caputo sense.Minimization of

Some Historical Aspects of Error Calculus by Dirichlet Forms [PDF]

, 2013
We discuss the main stages of development of the error calculation since the beginning of XIX-th century by insisting on what prefigures the use of Dirichlet forms and emphasizing the mathematical properties that make the use of Dirichlet forms more ...

Extended biorthogonal matrix polynomials [PDF]

Mathematica Moravica, 2017
The pair of biorthogonal matrix polynomials for commutative matrices were first introduced by Varma and Tasdelen in [22]. The main aim of this paper is to extend the properties of the pair of biorthogonal matrix polynomials of Varma and Tasdelen and ...

An Overview of the Pathway Idea and Its Applications in Statistical and Physical Sciences

Axioms, 2015
Pathway idea is a switching mechanism by which one can go from one functional form to another, and to yet another. It is shown that through a parameter α, called the pathway parameter, one can connect generalized type-1 beta family of densities ...

THE USE OF PARABOLIC SPLINEES IN CAD OF LINEAR STRUCTURES

Российский технологический журнал, 2018
The article continues studying the problem of the calculus of variations that occurs in line structures routing, in particular, roads. The task is to find a line that satisfies all technical constraints and gives a minimum of a given functional, for ...

Bosonization method for second super quantization

, 2009
A bosonic-fermionic correspondence allows an analytic definition of functional super derivative, in particular, and a bosonic functional calculus, in general, on Bargmann- Gelfand triples for the second super quantization.

On the index of pseudo-differential operators on compact Lie groups [PDF]

, 2019
In this note we study the analytical index of pseudo-differential operators by using the notion of (infinite dimensional) operator-valued symbols (in the sense of Ruzhansky and Turunen).

Approximation of the Generalized Lame Equations by the Strain Energy Functional [PDF]

International Journal of Mathematical, Engineering and Management Sciences
This paper considers a linear system of partial differential equations (PDEs) to describe the stress-strain state of a two-phase body under static load, such as water-saturated soil.
