  There are two algebraic lower bounds of the number of n-periodic points of a
self-map f:M\to M of a compact smooth manifold of dimension at least 3 :
NF_n(f)=min {#Fix(g^n) ;g\sim f; g continuous} and NJD_n(f)=min {#Fix}(g^n)
;g\sim f; g smooth}}. In general NJD_n(f) may be much greater than NF_n(f). We
show that for a self-map of a semi-simple Lie group, inducing the identity
fundamental group homomorphism, the equality NF_n(f)=NJD_n(f) holds for all n
iff all eigenvalues of a quotient cohomology homomorphism induced by f have
moduli \le 1.
