%0 Journal Article %T The multiplicative inequality for class degrees via relative transition classes %A Soonjo Hong %J Mathematics %D 2014 %I arXiv %X Generalizing the notion of the degree of a finite-to-one factor code from a shift of finite type, the class degree of a possibly infinite-to-one factor extends many important properties of degree. In this paper, introducing class degree, we study how class degrees change as two factor codes are, in comparison with degrees. %U http://arxiv.org/abs/1411.5236v1
