Criteria equivalent to the Riemann Hypothesis
We give a brief overview of a few criteria equivalent to the Riemann
Hypothesis. Next we concentrate on the Riesz and B{\'a}ez-Duarte criteria. We
proof that they are equivalent and we provide some computer data to support
them. It is not compressed to six pages version of the talk delivered by M.W.

The ternary Goldbach conjecture is true
The ternary Goldbach conjecture, or three-primes problem, asserts that every
odd integer greater than is the sum of three primes. The present paper
proves this conjecture.
Both the ternary Goldbach conjecture and the binary, or strong, Goldbach
conjecture had their origin in an exchange of letters between Euler and
Goldbach in 1742. We will follow an approach based on the circle method, the
large sieve and exponential sums. Some ideas coming from Hardy, Littlewood and
Vinogradov are reinterpreted from a modern perspective. While all work here has
to be explicit, the focus is on qualitative gains.
The improved estimates on exponential sums are proven in the author's papers
on major and minor arcs for Goldbach's problem. One of the highlights of the
present paper is an optimized large sieve for primes. Its ideas get reapplied
to the circle method to give an improved estimate for the minor-arc integral.Comment: 79 pages, 1 figure. Minimal change
Light-Weight Hierarchical Clustering Middleware for Public-Resource Computing
The goal of this work was to investigate ways to implement and improve a public-resource computing middleware. Specifically, to make hosting a public-resource computing project logistically simpler and to examine the affect of hierarchical clustering on bandwidth utilization at the central server. To this end, we present the architecture for our cross-platform, multithreaded public-resource computing middleware. Implementing and debugging the middleware proved far more challenging than initially anticipated. As hard as debugging multithreaded programs is, our experience has shown us that it can be leveraged to simplify system components. Our main contribution is the final system architecture.Computer Science Departmen
