Abstract
We study the periodicity of signs of Fourier coefficients of the function,. where αis a positive integer, f(-q)=Πn=1∞(1-qn), and rd∈Z. As an application, we will prove the periodicity of signs for the crank differences conjectured by G.E. Andrews and R. Lewis and for the weighted counts of certain types of partitions.
