    f-Frequently hypercyclic \(C_{0}\) -semigroups on complex sectors

    We analyze f-frequently hypercyclic, q-frequently hypercyclic ( \(q> 1\) q > 1 ), and frequently hypercyclic \(C_{0}\) C 0 -semigroups ( \(q=1\) q = 1 ) defined on complex sectors,with values in sepa...

    Abstract time-fractional equations: Existence and growth of solutions

    We contribute to the existence theory of abstract time-fractional equations by stating the sufficient conditions for generation of not exponentially bounded α-times C-regularized resolvent families (α > 1) in seq...
