We consider the topological space of composition operators C(H2) on the Hardy space H2(D) of the unit disc D with operator norm topology. We prove a necessary condition for two composition operators to lie in the same path components and as a consequence we are able to determine path components of composition operators induced by analytic self-maps of the unit disc D which are analytic in a nei...

Objective: This study was conducted to evaluate the effects of different proportions of marshmallow extract (Althaea officinalis L.) on growth performance and carcass composition of common carp (Cyprinus carpio). Methods: Common carp with an average weight of 37.65 ± 4.40 g were fed for two months with a diet supplemented with marshmallow (A. officinalis) ext...

This paper restates the results on fuzzy relation equations with sup-inf composition from the viewpoint of decomposition, presents a way to describe the solution set of fuzzy relation equations, and shows a necessary and sufficient condition, which partly answers the open problem for existence of minimal solutions over complete Brouwerian lattices. Keywords— Complete Brouwerian lattice, fuzzy r...
