Mind Duggal Transforms

Abstract

It is known that if an operator TT is complex symmetric then its Aluthge transform is also complex symmetric. This Note is devoted to showing that the Duggal transform doesn't inherit this property. For instance, we'll show that the Duggal transform isn't always complex symmetric when TT is, as it was claimed in \cite{Ga}.
