"On the normal number of prime factors of Ramanujan Tau function"

We will discuss various results concerning ω(τ(p)), ω(τ(n)), ω(τ(p+1)) where τ denotes Ramanujan Tau function and ω(n) denotes the number of prime factors of n counted without multiplicity. This is work in progress with Prof. Ram Murty.

"Triple linking numbers and surface systems"

We relate fillability of two link exteriors, and the question when two links admit homeomorphic surface systems to (a refinement of) Milnor’s triple linking numbers. This extends a theorem of Davis-Roth to include also links with non-vanishing linking numbers. This is joint work with C. Davis, P. Orson, and M. Powell.
