On the optimal control of systems governed by quasilinear integro-partial differential equations of parabolic type

Journal of Mathematical Analysis and Applications, 1977
AbstractRecently, M. N. Oğuztöreli presented certain results on the existence and uniqueness of solutions of systems governed by a linear integro-partial differential equation of parabolic type with delayed arguments. Since his results admit only smooth coefficients, they could not be used directly in the study of the optimal control problems with ...

On Martínez-Kaabar fractal-fractional double Laplace transformation

Ain Shams Engineering Journal
An extended version of the Martinez-Kaabar fractal-fractional (MKF-F) calculus theory is investigated in this work, to the integral transformations and employed in solving some fractal-fractional (F-F) partial integro-differential equations. Specifically,

Phase‐Lag Integro‐Partial Differential Equation: Local and Nonlocal Solutions

Advances in Mathematical Physics
Nonlocal information, such as material deformation, genetic genes, or the history of the disease, are essential as they provide us with additional details that increase the numerical solution’s accuracy. With the help of the phase delay, we may also predict the future of the phenomena we are researching.

Bounds of Certain Dynamic Inequalities on Time Scales

International Journal of Analysis and Applications, 2014
In this paper we study explicit bounds of certain dynamic integral inequalities on time scales. These estimates give the bounds on unknown functions which can be used in studying the qualitative aspects of certain dynamic equations.

MODELING OF ELECTROMAGNETIC WAVES PROPAGATION IN THE MEDIUM WITH SPACE DISPERSION

Informatika, 2017
A mathematical model describing the propagation of electromagnetic waves in the medium with space dispersion is being developed. Modeling is based on the transformation of integro-differential equations of monochromatic electrodynamics for the fields in ...

Exponential Stability of Two Coupled Second-Order Evolution Equations

Advances in Difference Equations, 2011
By using the multiplier technique, we prove that the energy of a system of two coupled second order evolution equations (one is an integro-differential equation) decays exponentially if the convolution kernel decays exponentially. An example is give to

Certain families of differential equations associated with the generalized 1-parameter Hermite–Frobenius Euler polynomials

Mathematical and Computer Modelling of Dynamical Systems
This study introduces a new approach to the development of generalized 1-parameter, 2-variable Hermite–Frobenius–Euler polynomials, which are characterized by their generating functions, series definitions and summation formulae.
