| Along with the rapid development of the computer and our country’s science, Combin-atorial Mathematics, as a kind of science research tools, is used more and more widely. Rior-dan matrix is a kind of important matrix,we can describe combinatorial numbers with two fu-nctions by using Riordan matrix,change the discussing of combinatorial numbers into the dis-cussing of matrix.In this paper, we generalize the concept of Riordan matrices to a kind of matrix sequenceand study the pattern problems of arrangements.The contents can be summarized as follows:In chapter â… , we introduce the background of Riordan matrix, then give the concept of ge-nerating function and give some generating function of important combinatorial numbers.Chapterâ…¡ can be divided into four sections: first we give the concept and property of R-iordan matrix,then we define one kind of matrix sequence:[g (x), f (x)], and then give someproperty of the sequence. Finally,we use this kind of matrix sequence to discuss somecombinatorial identities.In chapter â…¢, we introduce pattern problems of permutations,it is the basis of theproblems of arrangement patterns.Chapter â…£ we use Riordan matrix to study the problems of arrangement patterns. |
