Abstract

Let b_m(n) denote the number of partitions of n into powers of m. Define σ_r=ε₂m²+ε₃m³+...+ε_rm^r, where ε_i=0 or 1 for each i. Moreover, let c_r=1 if m is odd, and c_r=2^r-1 if m is even. The main goal of this paper is to prove the congruence b_m(m^r+1n-σ_r-m)≡0 (modm^r/c_r). For σ_r=0, the existence of such a congruence was conjectured by R. F. Churchhouse some 30 years ago, and its truth was proved by Ø. J. Rødseth, G. E. Andrews, and H. Gupta soon after.
