In this thesis, we are primarily concerned with an algorithm, due to Kohn, for finding subelliptic multipliers in the theory of several complex variables. Kohn's work applies to rings of germs of smooth functions. A special ...

The techniques of algebraic geometry have been widely and successfully applied to the study of linear codes over finite fields since the early 1980's. Recently, there has been an increased interest in the study of linear ...

A filling subgroup of a finitely generated free group F(X) is a subgroup which does not fix a point in any very small action free action on an R-tree. For the free group of rank two, we construct a combinatorial algorithm ...

Above all, our work presents very explicit results, mostly stated as formulae and explicit representations, rather than algorithms. The formulae that we obtained for the ramifications and an integral basis of a cyclic ...

In their 1995 paper, Muller and Schupp define the concept of an alternating automaton, a sort of completion of the notion of a non-deterministic automaton, and show how the notion may be used to prove a number of major ...

The Main Theorem shows that every nontrivial tame knot in R3 has an alternating quadrisecant. This result refines the previous work about quadrisecants and gives greater geometric insight into knots. The Main Theorem ...

An (omega)-language is a set of infinite ((omega)-type) strings of symbols. We study the classes of (omega)-languages accepted by Turing Acceptors when infinite computations are allowed. There are various possible ...

In 1877, R. Dedekind introduced the sum$$s(d, c) = \sum\sbsp{j=1}{c}\left(\left({j\over c}\right)\right)\left(\left({dj\over c}\right)\right),$$which appears in the multiplier system of the Dedekind eta-function as a modular ...

Two algorithms of use in sparse matrix computation are studied. The rounding errors of the computational Lanczos algorithm are examined in order to account for the differences between the ideal and the machine-operator ...

In this thesis, we provide connections between analytic properties in Euclidean R^n and analytic properties in sub-Riemannian Carnot groups. We introduce weak s-John domains, in analogy with weak John domains, and we prove ...

In this paper we examine an approximation of the Maxwell-Boltzmann equation for a 1D gas. In the manner of classical gas dynamics, we derive a balance law and use it to determine the grossly determined solutions, a sub-class ...

In 1983, Bhatia, Davis and McIntosh proved that if A and B are self-adjoint with dist($\sigma(A),\sigma(B)) \geq \delta$ then there is some $c\sb{sa} < 2$ (independent of A and B) such that $c\sb{sa}\vert\vert\vert AQ - ... application/pdf PDF (3MB) • (1950) application/pdf PDF (2MB) • (2013-05-24) We study vortex equations with a parameter$s$on smooth vector bundles$E$over compact K\"ahler manifolds$M$. For each$s\$, we invoke techniques in \cite{Br} by turning vortex equations into the elliptic partial ...
