Strong Ellipticity and Infinitesimal Stability within Nth-Order Gradient Elasticity
Mathematics, 2023 We formulate a series of strong ellipticity inequalities for equilibrium equations of the gradient elasticity up to the Nth order. Within this model of a continuum, there exists a deformation energy introduced as an objective function of deformation ...

Strong Stability Preserving Integrating Factor Two-Step Runge–Kutta Methods [PDF]
Journal of Scientific Computing, 2019 Problems with components that feature significantly different time scales, where the stiff time-step restriction comes from a linear component, implicit-explicit (IMEX) methods alleviate this restriction if the concern is linear stability.

DECOMPOSITION OF Cm THROUGH Q-PERIODIC DISCRETE EVOLUTION FAMILY [PDF]
Matrix Science Mathematic, 2019 Let U={U (m,n) : m,n ∈ Z+} n≥m≥0 be the q-periodic discrete evolution family of square size matrices of order m having complex scalars as entries generated by L(C^m-valued, q-periodic sequence of square size matrices (An)n∈Z+ where q≥2 is a natural ...

On strong stability of explicit Runge–Kutta methods for nonlinear semibounded operators [PDF]
IMA Journal of Numerical Analysis, 2018 Explicit Runge–Kutta methods are classical and widespread techniques in the numerical solution of ordinary differential equations (ODEs). Considering partial differential equations, spatial semidiscretizations can be used to obtain systems of ODEs that

Embedded pairs for optimal explicit strong stability preserving Runge-Kutta methods [PDF]
Journal of Computational and Applied Mathematics, 2018 We construct a family of embedded pairs for optimal strong stability preserving explicit Runge-Kutta methods of order $2 \leq p \leq 4$ to be used to obtain numerical solution of spatially discretized hyperbolic PDEs.

On asymptotic properties of solutions for differential equations of neutral type
Современная математика: Фундаментальные направления, 2023 The stability of systems of linear autonomous functional differential equations of neutral type is studied. The study is based on the well-known representation of the solution in the form of an integral operator, the kernel of which is the Cauchy ...

Strong stability in retrial queues [PDF]
Theory of Probability and Mathematical Statistics, 2004 The authors study the strong stability in retrial queues after perturbation of retrial parameters. Queueing systems, in which customers who find all servers and waiting positions (if any) occupied may retry for service after a period of time, are called retrial queues.
