Abstract : The tensor product $A\otimes B$ of Hilbert space operators $A$ and $B$ will be shown to be log-hyponormal if and only if $A$ and $B$ are log-hyponormal. Some general comments about generalized hyponormality are also made.
Keywords : tensor product, log-hyponormal, $w$-hyponormal, $p$-quasi-hyponormal
