I will discuss a varient of the mixed Littlewood Conjecture, namely one relating to a `pseudo-absolute value' sequence, and how it can be solved under certain restrictions on this sequence. The method appeals to a measure rigidity theorem of Lindenstrauss and relies upon being able to prove the existance of some ergodic measure with positive entropy. Time permitting, I will also describe a metrical result complementing the mixed Littlewood Conjecture itself.
