Bogdan Gheorghe's page
Hi, My name is Bogdan and I am a Postdoctoral fellow at the Max Planck Institute in Bonn. I obtained my PhD student in Mathematics at Wayne State University under the supervision of Dan Isaksen in 2017.
I am working in motivic homotopy theory (mostly over Spec C) from an algebraic topology viewpoint (cellular methods, Adams spectral sequence, ring spectra, chromatic methods, etc), and am in particular interested in nilpotence and periodicity in motivic homotopy theory.
My email address is firstname.lastname@example.org, feel free to ask me for an updated CV.
Some (rather old...) notes and slides:
