Symmetry Protected Topological phase (SPT) is a special kind of quantum phase protected by symmetry and has a clear bulk-boundary correspondence relation. For 2d bosonic SPT theory, its boundary theory is well studied because there is only one input data in bosonic case. However, a 2d fermionic SPT (FSPT) theory has three different input data and constructing a boundary theory for 2d FSPT in general is difficult. In this talk, I will discuss an idea using a bosonic model which carries the input data of a FSPT theory to construct a boundary theory for 2d FSPT.
