Properties of Multiplication Operators on Köthe spaces

René Erlin Castillo, Julio C. Ramos Fernández, Margot Salas-Brown

Published 2014-11-04Version 1

We make an exhaustive study of the properties of multiplication operator $M_u$ acting on K\"othe spaces. We characterize the multiplication operators, acting on K\"othe spaces, which are: bounded, injective, onto, bijective, Fredholm, compact, with closed range and with range finite. We also study the spectrum, the $n$-power and calculate the essential norm of $M_u$ and we study the algebra of multiplication operators.
