In a recent paper, Andrews and Newman extended the mex-function to integer
partitions and proved many partition identities connected with these
functions. In this paper, we present parity considerations of one of the
families of functions they studied, namely pt,t(n).
Among our results,
we provide complete parity characterizations of
p1,1(n) and p3,3(n).
