Triangulating Spun 2-Knot Complements
Rhuaidi Antonio Burke, Benjamin Burton, Arunima Ray +3
A -knot is an embedding of a -sphere into the -sphere. Similar to the case of embedding circles into the -sphere, this allows the -sphere to be knotted. In this shor…

Constructing locally flat surfaces in 4-manifolds
Arunima Ray
There are two main approaches to building locally flat embedded surfaces in 4-manifolds: direct methods which geometrically manipulate a given map of a surface, and more indirect m…

Not all knots are smoothly round handle slice
Tye Lidman, Allison N. Miller, Arunima Ray
Freedman and Krushkal showed that if the surgery conjecture and the -cobordism conjecture hold for all topological 4-manifolds, then every link with pairwise zero linking number…
