A class of nonlocal impulsive differential equations with conformable fractional derivative
Cubo, 2022 In this paper, we deal with the Duhamel formula, existence, uniqueness, and stability of mild solutions of a class of nonlocal impulsive differential equations with conformable fractional derivative.

Polyhomomorphisms of locally compact groups [PDF]
Sbornik: Mathematics, 2020 Let and be locally compact groups with fixed two-sided invariant Haar measures. A polyhomomorphism is a closed subgroup with fixed Haar measure, whose marginals on and are dominated by the Haar measures on and .

Partial actions of groups and actions of inverse semigroups [PDF]
, 1995 Given a group G, we construct, in a canonical way, an inverse semigroup S(G) associated to G. The actions of S(G) are shown to be in one-to-one correspondence with the partial actions of G, both in the case of actions on a set, and that of actions as ...

Feller semigroups, Lp-sub-Markovian semigroups, and applications to pseudo-differential operators with negative definite symbols [PDF]
, 2001 The question of extending L-p-sub-Markovian semigroups to the spaces L-q, q > P, and the interpolation of LP-sub-Markovian semigroups with Feller semigroups is investigated.

On a certain class of semigroups of operators [PDF]
, 2010 We define an interesting class of semigroups of operators in Banach spaces, namely, the randomly generated semigroups. This class contains as a remarkable subclass a special type of quantum dynamical semigroups introduced by Kossakowski in the early ...

Operator splittings and spatial approximations for evolution equations [PDF]
, 2009 The convergence of various operator splitting procedures, such as the sequential, the Strang and the weighted splitting, is investigated in the presence of a spatial approximation. To this end a variant of Chernoff's product formula is proved.

Group Actions on Twisted Sums of Banach Spaces [PDF]
Bulletin of the Malaysian Mathematical Sciences Society, 2020 We study bounded actions of groups and semigroups G on exact sequences of Banach spaces from the point of view of (generalized) quasilinear maps, characterize the actions on the twisted sum space by commutator estimates and introduce the associated ...

Interactions in noncommutative dynamics [PDF]
, 1999 A mathematical notion of interaction is introduced for noncommutative dynamical systems, i.e., for one parameter groups of *-automorphisms of $\Cal B(H)$ endowed with a certain causal structure.

Dynamical Semigroups for Unbounded Repeated Perturbation of Open System [PDF]
, 2015 We consider dynamical semigroups with unbounded Kossakowski-Lindblad-Davies generators which are related to evolution of an open system with a tuned repeated harmonic perturbation.
