چکیده

We give a combinatorial interpretation for the super Catalan number S(m,m + s) for s ≤ 3 using lattice paths and make an attempt at a combinatorial interpretation for s = 4. We also examine the integrality of some factorial ratios.

Zarankiewicz Numbers and Bipartite Ramsey Numbers

The Zarankiewicz number z(b; s) is the maximum size of a subgraph of Kb,b which does not contain Ks,s as a subgraph. The two-color bipartite Ramsey number b(s, t) is the smallest integer b such that any coloring of the edges of Kb,b with two colors contains a Ks,s in the rst color or a Kt,t in the second color.In this work, we design and exploit a computational method for bounding and computing...

Super Ballot Numbers

The Catalan numbers C n = (2n)!/n! (n + 1)! are are well-known integers that arise in many combinatorial problems. The numbers 6(2n)!/n! (n + 2)!, 60(2n)!/n! (n + 3)!, and more generally (2r + 1)!/r! · (2n)!/n! (n + r + 1)! are also integers for all n. We study the properties of these numbers and of some analogous numbers that generalize the ballot numbers, which we call super ballot numbers.

Coefficients and Catalan Numbers

In this paper we establish some new congruences involving central binomial coefficients as well as Catalan numbers. Let p be a prime and let a be any positive integer. We determine P p a −1 k=0`2k k+d´mod p 2 for a −1 k=0`2k k+δ´mod p 3 for δ = 0, 1. We also show that 1 C n p a −1 X k=0 C p a n+k ≡ 1 − 3(n + 1) " p a − 1 3 « (mod p 2) for every n = 0, 1, 2,. .. , where C m is the Catalan number...

Generalized Factorial Functions and Binomial Coefficients

Let S ⊆ Z. The generalized factorial function for S, denoted n!S , is introduced in accordance with theory already established by Bhargava ([4]). Along with several known theorems about these functions, a number of other issues will be explored. This Thesis is divided into 4 chapters. Chapter 1 provides the necessary definitions and offers a connection between the generalized factorial function...
