This is the course webpage for Math304, Department of Mathematics, Simon Fraser University. Spring 2021. In this course we will investigate Rubik's cube, the 15-puzzle, TopSpin, and other permutation ...

Although naturally occurring proteins form stable defined tertiary structures, it is well known that many proteins with non-natural sequences have unstructured conformations 1,2. This suggests that ...

“What time is it?” is not a question that usually provokes a lot of soul-searching. It’s generally taken for granted that even if we don’t know the correct time, a correct time does exist and that ...

Why are walls always straight? Why does it cost so much to build them? And why do big construction projects so often run late? Construction has always been a conservative industry, used to doing ...

Abstract: Permutation entropy (PE) is a widely used metric for quantifying the complexity of time series data. Recent efforts have extended PE to graph signals, resulting in the graph permutation ...

Abstract: Understanding the underlying graph structure of a nonlinear map over a particular domain is essential in evaluating its potential for real applications. In this paper, we investigate the ...
