Abstract
The number of partitions of a bi-partite number into at mostj parts is studied. We consider this function,p j (x, y), on the linex+y=2n. Forj≤4, we show that this function is maximized whenx=y. Forj>4 we provide an explicit formula forn j so that, for alln≥n j ,x=y yields a maximum forp j (x,y).
