Andrew Moorhead (University of Kansas), Higher Kiss terms for modular varieties

Tue, 23 March 2021, 1 pm MDT

We explain how the $4$-ary Kiss term for a modular variety can be composed with itself to produce an infinite sequence of terms, each having a connection to a particular arity higher commutator that mimics the connection that the Kiss term has to the binary modular commutator. We will then discuss how these terms can be used to show that there is a greatest clone among those that share a sequence of Day terms, congruences, and higher commutator operations.
