The 2-variable truncated Tricomi functions
In this paper, we introduce 2-variable truncated Tricomi functionshn (x, y) and 2-parameter 2-variable truncated Tricomi functions h(α) n,ν(x, y) employing integral forms and establish their characteristics, such as series definitions and generating ...

Asymptotic expansions for variants of the gamma and Post–Widder operators preserving 1 and xj
Mathematical Methods in the Applied Sciences, Volume 47, Issue 18, Page 13718-13733, December 2024.Recently, the authors constructed operators acting on a space of functions defined on [0,∞)$$ \left[0,\infty \right) $$ and preserving 1 and xj$$ {x}^j $$ for a given j∈ℕ$$ j\in \mathrm{\mathbb{N}} $$. To this end, they considered suitable modifications of the Post–Widder and gamma operators.

Generalizations of Riemann–Liouville fractional integrals and applications
Mathematical Methods in the Applied Sciences, Volume 47, Issue 16, Page 12833-12870, 15 November 2024.The notion of a generalized Riemann–Liouville fractional integral is introduced, and its domain, range, and properties are studied. The new notion and properties provide new insight and understanding into the classical Riemann–Liouville fractional integral and its properties.

Қарағанды университетінің хабаршысы. Математика сериясы, 2020 As part of this scientific work, we study a displacement boundary value problem for a third - order parabolichyperbolic type equation with a third - order parabolic equation backward in time and a wave equation in the domain of hyperbolicity.

Asymptotics for the greatest zeros of solutions of a particular O.D.E.
Le Matematiche, 1994 This paper deals with the Liouville-Stekeloff method for approximating solutions of homogeneous linear ODE and a general result due to Tricomi which provides estimates for the zeros of functions by means of the knowledge of an asymptotic representation ...

Series and asymptotic analysis of the $k$-confluent hypergeometric differential equation
Electronic Journal of Qualitative Theory of Differential EquationsThis study investigates both the homogeneous and non-homogeneous forms of the $k$-confluent hypergeometric differential equation. In the neighborhood of the regular singular point, series solutions are constructed using the Frobenius method.

Space-time spectral collocation algorithm for solving time-fractional Tricomi-type equations
Open Physics, 2016 We introduce a new numerical algorithm for solving one-dimensional time-fractional Tricomi-type equations (T-FTTEs). We used the shifted Jacobi polynomials as basis functions and the derivatives of fractional is evaluated by the Caputo definition.
