Title: Hard vs easy algorithms: how does graph theory help us?
Abstract: In many sciences and practical applications we come across a particular type of a problem which involves finding a solution to a certain set of constraints (requirements) from the given pool of objects. In artificial intelligence, this type of problem is referred to as a Constraint Satisfaction Problem. Constraint satisfaction problems arise in areas as diverse as theoretical and applied mathematics, molecular physics, scheduling of events, assignment of radio frequencies, computational biology, mathematical linguistics, etc. of particular interest is the question of how difficult, from the computational point of view, an algorithm solving such a problem may be. In this talk, we will try to explain the connection between constraint satisfaction problems and certain mappings between graphs and the diverse approaches that can be used to study the computational complexity of the derived graph-theoretic problems.

Dr. Andrea Burgess, Department of Mathematics, Ryerson University
Title: Combinatorial designs and cycle decompositions
Abstract: In this talk, I will highlight some research directions related to combinatorial designs and cycle decompositions. Combinatorial designs originate in their application to the design of statistical experiments which test interactions between objects. In the case where objects to be compared are to be arranged in a circular manner (such as bacteria in Petri dishes), certain experiments can be modelled by cycle decompositions of graphs (also called cycle designs). Combinatorial designs also have applications to areas such as software testing, coding theory and communication systems. My work focuses largely on cycle decompositions of graphs, and properties of decompositions including resolvability, colouring and intersection properties

Sebastian Ferrando, Department of Mathematics, Ryerson University
Title: Non probabilistic Pricing and Nonlinear Risk Estimation.
Abstract: The presentation describes two main lines of research available to students. One line of research involves mathematical investigations of new non probabilistic models to price financial instruments. These investigations require a solid knowledge of analysis and probability. Associated numerical work will also be described that complements the theoretical investigations, this numerical work requires advanced programming skills. Another line of research involves the software implementation of a nonlinear estimator to assess the effect of a vector of risk factors on a given portfolio. This investigation requires advanced programming capabilities as well as knowledge of linear algebra and functional analysis.

Thursday, November 1, 12:10-12:30, 2012, ENG 210.
Katrin Rohlf, Department of Mathematics, Ryerson University Title: Exploring the breakdown of continuum descriptions
Abstract: The goal of this talk is to highlight some of my current research in the areas of blood flow, and chemically reacting media. The first part of the talk will provide an overview of the main motivation of the research, namely blood flow in small vessels. Traditional continuum descriptions in the form of partial differential equations (Newtonian and non-Newtonian flow models) will be discussed at a very basic level, and the need for exploring the breakdown of such descriptions for blood will be explained. The next part of the talk describes a particle-based fluid flow model that can be used to explore the breakdown of the continuum descriptions. This is particularly important for blood flow in complex geometries, but has applications in other areas such as chemical systems as well. Highlights of recent results, current work and future directions will form the final parts of this seminar.

Thursday, November 1, 1:10-1:30, 2012, ENG 210.
Anthony Bonato, Department of Mathematics, Ryerson University$ Title: Modelling, mining, and searching networks
Abstract: Abstract: Complex networks arise in many diverse contexts, ranging from web pages and their links, protein-protein interaction networks, and on-line social networks such as Facebook and LinkedIn. The modelling and mining of these large-scale, self-organizing systems is a broad effort spanning many disciplines. A number of common properties have been observed in complex networks, such as power law degree distributions and the small world property. Stochastic graph models simulate these properties, while expanding our theoretical understanding of random graph models. Models for complex networks also give insight into their underlying properties.

Abstract: We discuss the evolution of models of financial markets from Louis Bachelier' pioneer wo$ developments. We show some examples about the practical use of these models in pricing and risk management. Also we provide an insight of our Financial Mathematics group, here in the department of Mathematics at Ryerson, and comment $ two possible topics for a Master Thesis.
