This paper presents a practical method of adding problem-specific notation to an established computer language. Our idea is to use unrestricted operator overloading as a tool to map the problem domain notation directly into an existing programming language. Our method introduces new operator symbols and function names into a host language by overloading existing usage. We extend the host progra...

Abstract This short note is concerned with various operator representations of frames in a Hilbert space $${{{\mathcal {H}}}}.$$ H . While it known that only very special can be represented the form $$\{ T^n \varphi \}_{n=0}^\infty $$ { <m...

Abstract It is shown that the extensions of exactly-solvable quantum mechanical problems connected with replacement ordinary derivatives by Dunkl ones and classical orthogonal polynomials exceptional can be easily combined. For such a purpose, example oscillator on line considered three different types rationally-extended oscillators are constructed. The corresponding wavefunctions expressed in...

‎In this paper‎, ‎using a generalized translation operator‎, ‎we obtain a generalization of Younis Theorem 5.2 in [3] for the Cherednik-Opdam transform for functions satisfying the $(delta,gamma,p)$-Cherednik-Opdam Lipschitz condition in the space‎ ‎$L^{p}_{alpha,beta}(mathbb{R})$.
