Supplement to the decomposition of the spaces of cusp forms of half-integral weight and trace formula of Hecke operators

In the previous paper [U], we calculated the trace of the Hecke operator $\tilde{T}_{k+1/2,N,\chi }(n^{2})$ on the space of cusp forms $S(k + 1/2, N, \chi )$ of half-integral weight under the assumption $\chi ^{2} = 1$. The purpose of this calculation is to find a relation between these traces …
