Differential operators, pullbacks, and families of automorphic forms [PDF]

open access: yes, 2015
This paper has two main parts. First, we construct certain differential operators, which generalize operators studied by G. Shimura. Then, as an application of some of these differential operators, we construct certain p-adic families of automorphic ...

Coherent Amplification of Optical Pulses in Metamaterials [PDF]

open access: yes, 2009
In this paper we theoretically study propagation of steady state ultrashort pulse in dissipative medium. We considered two cases (i) medium consists of lossy metallic nanostructures embedded into a gain material and (ii) the gain material is embedded ...

Stability Analysis of an LTI System with Diagonal Norm Bounded Linear Differential Inclusions

open access: yesSymmetry, 2021
In this article, we present a stability analysis of linear time-invariant systems in control theory. The linear time-invariant systems under consideration involve the diagonal norm bounded linear differential inclusions. We propose a methodology based on

A Differential Algebraic Method to Approximate Nonsmooth Mechanical Systems by Ordinary Differential Equations

open access: yesJournal of Applied Mathematics, 2013
Nonsmooth mechanical systems, which are mechanical systems involving dry friction and rigid unilateral contact, are usually described as differential inclusions (DIs), that is, differential equations involving discontinuities.

Stability radius of second order linear structured differential inclusions

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
For arbitrary second order square matrices $A, B, C$; $A$ Hurwitz stable, the minimum positive value $R$ for which the differential inclusion $$\dot{x}\in F_{R}(x):=\{(A+B\Delta C)x, \ \Delta \in \mathbb{R}^{2\times 2},\ \|\Delta \| \le R \}$$ fails to ...

A Multi-Scale, Semi-Analytical Model for Transient Heat Transfer in a Nano-Composite Containing Spherical Inclusions

open access: yesEurasian Chemico-Technological Journal, 2019
This paper presents a semi-analytical model for transient heat conduction in a composite material reinforced with small spherical inclusions. Essential to the derivation of the model is the assumption that the size of the inclusions is much smaller than ...

Regularization of inclusions of differential equations solutions based on the kinematics of a vector field in stability problems

open access: yesJournal of Physics: Conference Series, 2021
This paper presents the new results of computing the inclusions of sets of solutions of ordinary differential equations corresponding to perturbations acting on the solutions of the system.

Multipole polarizability of a graded spherical particle [PDF]

open access: yes, 2005
We have studied the multipole polarizability of a graded spherical particle in a nonuniform electric field, in which the conductivity can vary radially inside the particle.

Existence of weak solutions to stochastic evolution inclusions [PDF]

open access: yes, 2004
We consider the Cauchy problem for a semilinear stochastic differential inclusion in a Hilbert space. The linear operator generates a strongly continuous semigroup and the nonlinear term is multivalued and satisfies a condition which is more heneral than
