The Pacific Northwest Geometry Seminar is sponsored by the following participating institutions: Lewis and Clark College, Oregon State University, Pacific University, Portland State University, Seattle University, University of British Columbia...

In this talk we discuss two backward uniqueness theorems for extrinsic geometric flow of possibly non-compact hypersurfaces in general ambient complete Riemannian manifolds. These are applicable to a wide range of extrinsic geometric flow, including...

It is conjectured that many models of statistical mechanics have a rich, fractal-like behaviour at and near their points of phase transition, with power-law scaling governed by critical exponents that are expected to depend on the dimension but not...

Let 𝔽_q be a finite field, and let ℙ²(𝔽_q) denote the projective plane over 𝔽_q. A subset B ⊆ ℙ²(𝔽_q) is called a blocking set if it intersects every line defined over 𝔽_q. Given an algebraic plane curve C in ℙ², under what...

In this talk, we will discuss how Ricci flow smoothing can be used to produce expanding Ricci solitons coming out of a metric cone, when the curvature is non-negative. We will discuss how its relation to problem in Hamilton-Lott pinching conjecture...

Mathematical modelling is increasingly central to pharmaceutical research and development through the framework of model-informed drug development (MIDD). This talk will introduce the core principles of MIDD and showcase its practical application...

In this article we study the double dimer model on hyperbolic Temper- leyan graphs via circle packings. We prove that on such graphs, the weak limit of the dimer model exists if and only if the removed black vertex from the boundary of an exhaustion...

The Calabi-Yau theorem says that given any smooth representative Φ of the first Chern class, there exists a unique K\”ahler metric ω cohomologous to α such that Ricci(ω)=Φ. It is natural to investigate whether similar results hold when the manifolds...

Many cells in our body migrate - 'good' examples are wound healing, embryogenesis and immune response; 'bad' example is metastasis. Migration starts with leading edge protrusion, which is enabled by branching growth of actin network and resisted by...
