For finite matrices ##A## and ##B## we have
Tr(AB)=Tr(BA)
What happens in case of infinite matrices?
Tr(AB)=Tr(BA)
What happens in case of infinite matrices?
The discussion centers around the properties of the trace function in the context of infinite matrices, specifically questioning whether the property Tr(AB) = Tr(BA) holds in this scenario.
Participants do not appear to reach a consensus on whether the trace property holds for infinite matrices, and multiple viewpoints and references are presented without resolution.
The discussion lacks clarity on the assumptions required for the trace function to be applicable to infinite matrices, and the relevance of the trace class operator is not fully explored.
