Complex Devaraj numbers
Recall that if N = p_1*p_2....p_r and if ((P_11)*(N1)^(r2)/((p_21)… (p_r1)) is an integer then N is a Devaraj number. Q: are there complex Devaraj numbers? Yes here is an example: N = (2  I)*((3 + 2*I)*(4I)= 33  4*I is a Devaraj number since
((1I)*(32 4*I)/(2+3*I)*(3I)) = 1 5*I, a Gaussian integer.

Naming things after yourself is a wellpaved path to warn others from paying any attention to you.

Naming things after yourself also is a first sign that the thread should go to Misc. Math.
