摘要：
A q-analogue of Sudarshan's diagonal representation of the quantum mechanical density matrix is obtained using q-boson coherent states. Earlier result of Mehta and Sudarshan on the self reproducing property of rho(z', z) is also generalized and a self-consistent self-reproducing kernel (K) over tilde (z', z) is constructed.
