On the Complexity of the Word Problem for Automaton Semigroups and Automaton Groups
, 2017 In this paper, we study the word problem for automaton semigroups and automaton groups from a complexity point of view. As an intermediate concept between automaton semigroups and automaton groups, we introduce automaton-inverse semigroups, which are ...

Control of Open Quantum Systems via Dynamical Invariants
Advanced Quantum Technologies, Volume 9, Issue 2, February 2026.Dynamical invariants are used to reverse‐engineer control fields for open quantum systems described by time‐dependent Lindblad master equations. By minimizing an analytic leakage functional, the protocol dynamically steers the state along an effectively decoherence‐free path without costly iterative propagation.

Self-restricting Noise and Exponential Relative Entropy Decay Under Unital Quantum Markov Semigroups [PDF]
QuantumStates of open quantum systems often decay continuously under environmental interactions. Quantum Markov semigroups model such processes in dissipative environments.

A universal example for quantitative semi‐uniform stability
Journal of the London Mathematical Society, Volume 113, Issue 2, February 2026.Abstract We characterise quantitative semi‐uniform stability for C0$C_0$‐semigroups arising from port‐Hamiltonian systems, complementing recent works on exponential and strong stability. With the result, we present a simple universal example class of port‐Hamiltonian C0$C_0$‐semigroups exhibiting arbitrary decay rates slower than t−1/2$t^{-1/2}$.

Tight Representations of 0-𝐸-Unitary Inverse Semigroups
Abstract and Applied Analysis, 2011 We study the tight representation of a semilattice in {0,1} by some examples. Then we introduce the concept of the complex tight representation of an inverse semigroup 𝑆 by the concept of the tight representation of the semilattice of idempotents 𝐸 of 𝑆 ...

Construction of propagators for divisible dynamical maps
New Journal of Physics, 2021 Divisible dynamical maps play an important role in characterizing Markovianity on the level of quantum evolution. Divisible maps provide an important generalization of Markovian semigroups. Usually one analyzes either completely positive or just positive

Semidistributive Inverse Semigroups, II [PDF]
, 2011 The description by Johnston-Thom and the second author of the inverse semigroups S for which the lattice LJ(S) of full inverse subsemigroups of S is join semidistributive is used to describe those for which (a) the lattice L(S) of all inverse ...

Heat kernels on metric graphs and a trace formula
, 2007 We study heat semigroups generated by self-adjoint Laplace operators on metric graphs characterized by the property that the local scattering matrices associated with each vertex of the graph are independent from the spectral parameter.
