Calculating extinction probabilities for the single birth chain with a reflecting barrier in a random environment
2.
The characteristic numbers and their probability meaning of the birth and death process with zero as its quasi - leap - reflecting barrier have been partially settled by professor yang in [ 1 ] , which depends on setting up a method that solving system of liner equations with two boundaries . in this thesis , the author has setted up another method that solving system of liner equations with one boundary on the basis of the former method , and has improved further the characteristic numbers and their probability meaning of the birth and death process with zero as its quasi - leap - reflecting barrier
