Research output: Contribution to journalArticlepeer-review


We study a certain class of embedded 2-foams that arise from gluing disks into ribbon torus knots along nonintersecting torus meridians. We exhibit several equivalent diagrammatic formalisms for these objects and identify several of their invariants, including a unique prime factorization.
