Michael Tsatsomeros will discuss a bounded region E(A) in the complex plane that contains the eigenvalues of a complex matrix A. E(A) is the intersection of an infinite number of regions defined by elliptic curves that were borne in Victoria many...

For the potential games there exists a potential function derived from the payoff variation of those players who modify their strategies. First we survey the general features of these games and discuss the evaluation of potential for some cases...

Quantum computers are hypothetical devices based on quantum physics that can out-perform classical computers. A famous algorithm by Peter Shor shows that quantum computers can factor an n-digit integer in n³ steps, exponentially better than the...

During mechanical interaction with our environment, we have a perceptual experience that can be compared to that of audition or vision. The tactile modality is based on mechanics and on its infinite complexities. Feeling objects, like in vision and...

This seminar may be of interest to mathematicians and is included in this listing on behalf of the Earth & Ocean Sciences Department.Seismic imaging is an important geophysical tool for delineating and monitoring the earth’s subsurface structure and...

Each day we make many choices, often under time pressure and with poor information. How do we do this? The basic electro-chemistry of individual neurons and synapses in our brains is fairly well understood. The key problem is one of scale: how do...

Computer Graphics applications require mathematical models and simulation software that captures the qualitative, characteristic behavior of a physical system, even at very coarse discretizations. Our research group develops such numerical tools by...

The study of nonnegative polynomials is a basic problem in real algebraic geometry. Truncated moment problem is a classical question in real analysis. Symmetric tensor decompositions are of interest in many areas of applied mathematics. The main goal...

The term “tipping point” describes the moment when a system suddenly changes state, with no obvious trigger other than a slowly changing environment. Tipping points are difficult to predict and difficult to reverse. Examples range from capsizing...
