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.

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.
