In Spring 2020, we began a study focused on the development of inclusive teaching practices in an undergraduate chemistry lecture course for non-STEM students. In the wake of the COVID-19 pandemic and ensuing educational disruptions, we changed the d

We give a construction of Gusarov's groups [Gscr ] n of knots based on pure braid commutators, and show that any element of [Gscr ] n is represented by an infinite number of prime alternating knots of braid index less than or equal to n +1. We also s

We complete the characterization of essential tori in link complements which was first given in [3], and give a new set of interesting and subtle examples of essential tori.

Dror Bar-Natan and Ofer Ron have questioned the accuracy of the statement on page 453, line 2 minus of my paper "Groups of Ribbon Knots", Topology Vol 37, No. 2, 441-458, that "It follows from the inductive proof that $\cal{R}_n$ is of index 2." See

Given a positive integer $n$, we say that two knots are $V_n$-equivalent if they have the same Vassiliev invariants of order $\le n$. We showed that the $V_n$-equivalence classes of ribbon knots form a group, the operation being induced by the connec
