The main result is a weighted quantization formula in the presence of commuting Hamiltonian actions. The corresponding Morse type inequalities in holomorphic situations are also established.Differential GeometrySymplectic reduction and a weighted multiplicity formula for twisted Spin$^c$-Dirac operatorstext
