This is a joint initiative between optimizers and mathematicians at Thompson Rivers University (TRU) and the University of British Columbia (UBC), Okanagan campus. 1:30-2:30: Yana Nec (TRU): Spike pattern as a window into non-injective transient...

The theory of large deviations provides with a way to compute asymptotically the probability that an interacting particle system moves from a given configuration to another one over a fixed time interval. The problem of finding the most likely...

Ginzburg–Landau theory is one of the oldest models in classical field theory for spontaneous symmetry breaking through the Higgs mechanism. Minimizers of the Ginzburg–Landau free energy, called vortices, are well-understood, especially in 2...

We discuss constructions based on finite fields of three types of combinatorial arrays: orthogonal, covering and ordered orthogonal arrays. Other combinatorial arrays have been similarly considered in the literature, including permutation arrays...

A celebrated theorem of Jorgens-Calabi-Pogorelov says that global convex solutions to the Monge-Ampere equation det(D^2u) = 1 are quadratic polynomials. On the other hand, an example of Pogorelov shows that local solutions can have line singularities...

The Arab mathematician al-Khwarizmi is usually said to be the 'father of algebra', or otherwise that 'the Arabs invented algebra'. There is probably nothing in the previous sentence that is true (except the 'usually'). It turns out that the...

One of the most important techniques provided by modern logic is the use of models to show the consistency of theories. The technique burst onto the scene in the late 19th century, and had its most important early instance in demonstrating the...

Hyperbolic Lattices are tessellations of the hyperbolic plane using, for instance, heptagons or octagons. They are relevant for quantum error correcting codes and experimental simulations of quantum physics in curved space. Underneath their...
