Source Sink Diffusion

Danielle Cox (MSVU)

We will introduce the diffusion process on graphs with the addition of sources and sinks. In particular, we will provide some results regarding the periodicity of the process. This is joint work with Todd Mullen (Dalhousie University), Shayne Breen (MSVU), Emily Wright (MSVU) and Jesse Preston (MSVU).

More Fun with the Sierpinski Relatives

Tara Taylor (StFX)

The Sierpinski gasket is a well-known fractal that can be described as the attractor of an iterated function system (IFS) that maps the unit square to three smaller squares (scaled down by 2). A Sierpinski relative is a fractal that is an attractor of an IFS that maps the unit square to three smaller squares but also involves the symmetries of the square. This is an interesting class of fractals because they all have the same fractal dimension but different topologies. Some are totally disconnected, some are disconnected with straight line segments, some are simply-connected, and some are multiply-connected. This very brief talk will explore different ways to compare and characterize the fractals that go beyond the fractal dimension. We will focus on the subclass that are disconnected with straight line segments, and this will involve convex hulls and epsilon-hulls.
