Synthetic equivariant spectra and complex bordism [25]

MPIM Topology Seminar [26]

I’ll discuss and motivate a theory of synthetic equivariant spectra in which equivariant stable homotopy types are suitably resolved by even-dimensional cells. This recovers the Adams—Novikov spectral sequence based on equivariant complex bordism and additionally admits an interpretation in terms of motivic homotopy theory over the complex numbers.

Mahler Measure and Numerical Semigroups [29]

PLeaSANT [30]

In this talk, we first review some classical results in the theory of the Mahler measure. Using classical results and assuming Lehmer’s conjecture, we then provide a proof of a conjecture due to P. Moree and A. Herrera-Poyatos.

We conclude by presenting some open questions concerning potential connections between Lehmer’s problem and the Mahler measure of polynomials arising from numerical semigroups.
