Abstract

We consider the self-similar measure μM,𝒟 generated by an expanding real matrix

M=(ρ-100ρ-1)M2()

and a digit set

𝒟={(00),(ab),(cd),(a+cb+d)}2.

In this paper, we study the spectral and non-spectral problems of μM,𝒟. In this case that (ab) and (cd) are two independent vectors, we prove that if ρ-1, then μM,𝒟 is a spectral measure if and only if ρ-12. For the case that (ab) and (cd) are two dependent vectors, we first give the sufficient and necessary condition for L2(μM,𝒟) to contain an infinite orthogonal set of exponential functions. Based on this result, we can give the exact cardinality of orthogonal exponential functions in L2(μM,𝒟) when L2(μM,𝒟) does not admit any infinite orthogonal set of exponential functions by classifying the values of ρ.
