摘要：In this talk, we will introduce directional sequence entropy and directional Kronecker algebra for Zq-systems. The relation between sequence entropy and directional sequence entropy are established. Meanwhile, direcitonal discrete spectrum systems and directional null systems are defined. It is shown that a Zq-system has directional discrete spectrum if and only if it is directional null. Moreover, it turns out that a Zq-system has directional discrete spectrum along q linearly independent directions if and only if it has discrete spectrum.
