Complex symmetric operators have attracted significant attention in recent years owing to their intriguing spectral properties and the elegance of their underlying mathematical structures. At their ...
Taiwanese Journal of Mathematics, Vol. 18, No. 1 (February 2014), pp. 277-283 (7 pages) Abstract In this paper, we obtain a necessary and sufficient condition for boundedness of composition operator ...
Every composition operator Cφ on the Lipschitz space Lip0(X) attains its norm. This fact is essentially known and we give in this paper a sequential characterization of the extremal functions for the ...
