Abstract: Abstract We show the existence of a doubly power-bounded T on L p , 1 p ∞ , p ≠ 2 , such that T is spectral of scalar type (hence polynomially bounded), T is… read more here.

Abstract: Abstract In the context of Hilbert space operators, there is a strong relationship between convex and expansive operators and 2-isometries. In this paper, we investigate the bounded linear operators T on a Hilbert space H… read more here.

Abstract: The existence and uniqueness of a local solution is proved for the incomplete Cauchy type problem to multi-term quasilinear fractional differential equations in Banach spaces with Riemann–Liouville derivatives and bounded operators at them. Nonlinearity in… read more here.
