摘要:
In a recent paper Chavez and Sahoo considered the functional equation f (ux - vy, uy v(x + y)) = f(x,y)f(u,v), which arose in a number theoretical context. Unfortunately one of their results is incorrect. Here we reconsider the equation on various domains. We observe that it is in fact a multiplicative Cauchy equation in disguise. We also point out some remaining open problems.
