Aram is an algebraic combinatorialist who uses order theory to better understand algebraic structures.
In 2011, Dyer put out a conjecture with an interesting consequence, that in order to understand the weak order of a Coxeter group, one can use the Bruhat order. Dyer formulated an operator which, conjecturally, would produce the join in the weak order when using the Hasse diagram of the Bruhat order. In this talk we describe this operator and give a (semi-)positive result to Dyer's conjecture. Note that no previous knowledge is assumed and all levels are welcome.
