Integral Characterizations for Uniform Stability with Growth Rates in Banach Spaces
Axioms, 2021 The aim of this paper is to present some integral characterizations for the concept of uniform stability with growth rates in Banach spaces. In this sense, we prove necessary and sufficient conditions (of Barbashin and Datko type) for an evolution ...

Branching Random Walks with One Particle Generation Center and Possible Absorption at Every Point
Mathematics, 2023 We consider a new model of a branching random walk on a multidimensional lattice with continuous time and one source of particle reproduction and death, as well as an infinite number of sources in which, in addition to the walk, only the absorption of ...

Polynomial stability of evolution operators in Banach spaces [PDF]
Opuscula Mathematica, 2011 The paper considers three concepts of polynomial stability for linear evolution operators which are defined in a general Banach space and whose norms can increase not faster than exponentially.

Geometric Operator Quantum Speed Limit, Wegner Hamiltonian Flow and Operator Growth [PDF]
Quantum, 2023 Quantum speed limits (QSLs) provide lower bounds on the minimum time required for a process to unfold by using a distance between quantum states and identifying the speed of evolution or an upper bound to it.

Large Time Decay of Solutions to a Linear Nonautonomous System in Exterior Domains
Mathematics, 2021 In this expository paper, we study Lq-Lr decay estimates of the evolution operator generated by a perturbed Stokes system in n-dimensional exterior domains when the coefficients are time-dependent and can be unbounded at spatial infinity.

Viability result for semilinear functional differential inclusions in Banach spaces
Karpatsʹkì Matematičnì Publìkacìï, 2021 We show the existence result of a mild solution for a semilinear functional differential inclusion, with viability, governed by a family of linear operators. We consider the case when the constraint is moving.

Using the Evolution Operator to Classify Evolution Algebras
Mathematical and Computational Applications, 2021 Evolution algebras are currently widely studied due to their importance not only “per se” but also for their many applications to different scientific disciplines, such as Physics or Engineering, for instance.

Quantum Time and Quantum Evolution
Universe, 2023 The problem of quantum time and evolution of quantum systems, where time is not a parameter, is considered. In our model, following some earlier works, time is represented by a quantum operator.
