(1993)Ramsey's Theorem states that if $P = \{C\sb1,\...,C\sb{n}\}$ is a partition of ($\omega\rbrack\sp{k}$ (the set of all unordered ktuples of natural numbers) into finitely many classes, then there exists an infinite set A ...

(1995)We establish a quadratic time algorithm for the word problem and a cubic time algorithm for the conjugacy problem for Coxeter groups of large type. We also give conditions on the relators of a largetype Coxeter group that ...

(1992)An independence system consists of a ground set and a collection of subsets of the ground set called independent sets with the property that any subset of an independent set is independent. We study the problem of computing ...

(1989)Representations of meromorphic functions as quotients of analytic functions have been studied for years. Miles showed that any meromorphic function f can be written as f$\sb1$/f$\sb2$ where each f$\sb{\rm j}$ is entire and ...

(1993)We present a new ChebyshevArnoldi algorithm for finding the lowest energy eigenfunctions of an elliptic operator. The algorithm, which is essentially the same for symmetric, nonsymmetric, and complex nonhermitian matrices, ...

(2004)Chapter 4 is devoted to finding new partition identities inspired by the work of O. Kolberg and S. Ramanujan. We use functions studied by N. J. Fine and R. J. Evans to construct analogues of modular equations, and then ...

(2004)We characterize a particular cascade by three indicies and show that the resulting powerlaw spectrum exponent depends on the indicies values only. The ensuing algebraic formula is remarkable for its simplicity.

(2003)The third part contains some applications, among them Hilberttype inequalities and inequalities of the form fx ≤cnsupy∈ Rfn y for bounded functions f with a spectral gap at the origin.

(1995)A ribbon knot is one which bounds a certain type of singular disk in the 3sphere. In this work we investigate an enumeration procedure for such disks and study a natural topological grouping of related ribbons which differ ...

(1987)Let K be a number of field with ring of integers o, and let G be a fixed finite group. If K$\sb\pi$ is a tame Galois Gextension, the integral closure ${\cal O}\sb\pi$ of o in K$\sb\pi$ is a locally free rank one oGmodule, ...

(2002)We explicitly characterize the family of networks for which such a protocol exists. This characterization is given in terms of forbidden rooted minors, which leads to a linear time recognition algorithm for this family of ...

(2004)We classify embeddings of algebraic groups as open orbits in affine varieties, generalizing results from toric geometry to connected reductive groups. In particular, we show that an embedding is determined by the set of ...

(2000)We consider two graphbased techniques for correcting the errors introduced into a transmission by a noisy channel. In the first technique, which is based on decoding with a layered graph known as a trellis, we examine ...
