Abstract. In this paper, we extend the notion of banded matrices to matrices where two bands are allowed, called double banded matrices. Our main aim is to establish the periodicity of the determinants for (0,1) double banded matrices. As a corollary, we answer to two recent conjectures and other extensions. Several illustrative examples are provided as well.
