摘要

We study some arithmetic properties on the set of \(\beta \) β -polynomials. Firstly, we give a sufficient condition for the finiteness of \(L_{\odot }\) L which represent the maximal finite shift after the comma for the product of two beta-polynomials. Secondly, we give explicit values of \(L_{\odot }\) L for families of Pisot basis.
