Moreover for the special case r = 0 we can further simplify formula (15) Because of 2ff for all integers ff, and 2ff 1 = 2ff 1) 2 for ff = 1# 2# : cf.

SUMMARY The purpose of this note is to derive distributional properties of the random variable associated with the number of time a simple random walk reaches a nonnegative height, where the random ....

....Under this assumption, we are able to offer an alternative proof of the following proposition, which appears in [5] and justifies the name Catalan monoid . Proposition 3.4 Let G be the graph 1 2 Delta Delta Delta n. Then the cardinality of C(G) is the nth Catalan number (defined in [15], page 101) Proof. If we write an element OE of C(G) as the pair of sequences M 1 M 2 Delta Delta Delta M k and q 1 q 2 Delta Delta Delta q k where M i is the top element of the kernel class of points which map to q i under OE (an example of which is illustrated below) 2 ....

Let C n be the n th Catalan number, i.e. C n = 1 n 1 # 2n n # ; 7. 4) e.g. 1, 1, 2, 5, 14, see Riordan [15]. The Catalan numbers have the self convolution property C n 1 = n # i=0 C i C n i , n # 1 (7.5) The Catalan numbers are also associated with the distribution of the number of customers served in an M M 1 busy period; see p. 65 of Riordan [14] We combine Theorem 7.1 and (7.2) to obtain the ....

....Applications to A r and D r basic hypergeometric series Probably, the most important application of matrix inversion is the derivation of hypergeometric series identities. There is a standard technique for deriving new summation formulas from known ones by using inverse matrices (cf. 1] 13] [26]) If (f nk ) n,k#Z r and (g kl ) k,l#Z r are lower triangular matrices being inverses of each other, then of course the following is true: X 0#k#n f nk a k = b n (5.1) MULTIDIMENSIONAL MATRIX INVERSIONS 257 if and only if X 0#l#k g kl b l = a k . 5.2) We expect that applications of ....
