Triple linking and rational homology cobordism
Ryan Stees
If a rational homology 3-sphere bounds a rational homology 4-ball , then the kernel of the inclusion-induced homomorphism is a Lagra…

Milnor's invariants for knots and links in closed orientable 3-manifolds
Ryan Stees
In his 1957 paper, John Milnor introduced a collection of invariants for links in detecting higher-order linking phenomena by studying lower central quotients of link groups…

Almost-concordance of knots in aspherical 3-manifolds
Ryan Stees
In this paper, we study topological concordance modulo local knotting, or almost-concordance, of knots in 3-manifolds . A. Levine, Celoria (arXiv:1602.05476v4), and Frie…
