    题目:On the degree of the subshifts of finite type on free semigroups I
    摘要:In this talk, we first recall some definitions and  important results on the degree of tree-shifts of finite type. Some familiar methods of proving such problem will be given and the detailed proof of our result will be given in the second talk.

    题目:On the degree of the subshifts of finite type on free semigroups II

    摘要:In this talk, we give an algebraic characterization of the degree of tree-shifts of finite type . An effective method, namely the systems of nonlinear recursive equations (SNRE) method, is introduced to compute the explicit value of the degree of a TSFT. This extends the previous result of D. Lind on one-dimensional SFTs and provides a new method of the study of multidimensional SFTs.
