Quasiperfect numbers with the same exponent

Number Theory 2017-11-30 v3

Abstract

We study some divisibility properties of quasiperfect numbers. We show that if N=(p1p2pt)2a=m2N=(p_1 p_2 \cdots p_t)^{2a}=m^2 is quasiperfect, then 2a+12a+1 is divisible by 33 and NN has at least one prime factor smaller than exp716.7944\exp 716.7944. Moreover, we find some lower bounds concerning quasiperfect numbers of the form N=m2N=m^2 with mm squarefree.
