Emilio Lauret

I am a mathematician working in Córdoba, Argentina. I was an Oberwolfach Leibniz Fellow at the Oberwolfach Mathematical Institute in 2013-2014 and an Alexander von Humboldt Postdoctoral Fellow at Humboldt-Universität zu Berlin in 2017-2018.

I am interested in the interaction between the spectrum of the Laplace operator and the geometry of a compact Riemannian manifold. I usually work with homogeneous spaces or locally homogeneous spaces, so the tools come from Lie theory.

Research interests:

  • Spectral geometry: isospectrality, spectral rigidity, spectra of homogeneous manifolds.
  • Lie theory: weight multiplicity formulas, branching rules.
  • Number theory: lattice point theorems, quadratic forms.
