【Abstract】 The property of birth and death Qmatrix in Markov processes is studied by using the theories and methods provided by functional analysis. It is proved that a birth and death Qmatrix generates a linear operator C0 semigroup, that is to say, the birth and death Qmatrix is the infinitesimal generator of the C0 semigroup. Therefore, the existence, uniqueness and stability of the solution of Kolmovgorov differential equations in Markov processes is verified.更多还原
