In the past four years, a number of immersed curve invariants have emerged in low-dimensional topology. Hanselman, Rasmussen and Watson used their immersed curve invariant for 3-manifolds with torus boundary to give an elegant proof of the fact that...

Narnaviruses have been described as positive-sense RNA viruses with a remarkably simple genome of ∼ 3 kb, encoding only a highly conserved RNA-dependent RNA polymerase (RdRp). Many narnaviruses, however, are ‘ambigrammatic’ and harbor an additional...

There will be a pre-talk from 1:20-1:50 Utah time to introduce symbolic dynamics and linear block growth. Pre-talk slides

In this talk, I report on recent work with Nathan Ng. Assuming a conjectural formula for a certain family of additive divisor sums, we prove an asymptotic formula for mean values of long Dirichlet polynomials with higher order shifted divisor...

In this talk I will present a "dynamical paradigm" for modeling networks of interacting genes and proteins that regulate every aspect of cell physiology. The paradigm is based on dynamical systems theory of nonlinear ODEs, especially one- and two...

Compressive sensing has generated tremendous amounts of interest since first being proposed by Emmanuel Candes, David Donoho, Terry Tao, and others a bit more than a decade ago. This mathematical framework has its origins in (i) the observation that...
