Title：An introduction to some recent results on group connectivity of signed  graphs

Abstract：This report focuses on some recent results in group connectivity of signed graphs. The main content of this report comes from the paper "Flow-contractible configurations and group connectivity of signed graphs" by Jiaao Li et al. The contents of this report are as follows. First, we give some classic conclusions in group connectivity of ordinary graphs. Second, we introduce group connectivity on signed graphs. Finally, we discuss the group connectivity of some families of signed graphs.
