Henrique N. Sá Earp



I am a Brazilian mathematician working at the Institute of Mathematics in Unicamp, University of Campinas, SP, Brazil. I am a principal investigator in research group GTAG - Gauge theory and algebraic geometry, led by Professor Marcos Jardim.

I study gauge theory over manifolds with special holonomy, particularly G2-manifolds. Related themes include asymptotically cylindrical Calabi-Yau geometry and nonlinear parabolic flows. I am generally interested in moduli problems of differential/ algebraic/ complex geometry and corresponding analytical methods; as well as applications to String/M-theory.

I have also done some collaborative work on Cartan decompositions applied to quantum information theory, geometry of surfaces applied to spectrometer designs, construction of spherical codes, and thermodynamics applied to ecological economics.

Besides mathematics, I am mostly involved with ecosocialism and Aikido.
