The Number of Modular H-Nielsen(2)

We have studied fπ₁(X,x₀),the self-homomorphism of π₁(X,x₀) led by self-mapping,the number of modular H-Nielsen is equal to Nielsen's number,if the normal covering space is led by H(f_π,π₁),the proper sepect subgr oup of π₁(X,x₀),and the process of calculate Nielsen's number with the number of modular H-Nielsen is shortened.
