| Abstract. I will discuss recent joint projects with Igor Dolinka, Des FitzGerald, Robert Gray, James Mitchell, and others, on planar diagram monoids. These include families such as Temperley-Lieb monoids, Kauffman monoids and Motzkin monoids. Questions considered include: What are the idempotents of these monoids? How many idempotents are there? What is the idempotent-generated submonoid? What it the minimal number of idempotents required to generate these submonoids? |
