I am a 2nd Year PhD student at the University Paris-Saclay. My CV.
My advisor is Prof. Kęstutis Česnavičius.


Rough pronunciation of my name:
Ar-nab (or-nob; or as in origin; nob as in 'noble')
Kun-du (coon-do; coon as in 'tycoon'; a hard 'd')

Interests:

My interests lie in the fields of Algebraic Geometry and Arithmetic Geometry. Currently, I am thinking about torsors under reductive group schemes on smooth algebras over valuation rings.

Here is my arXiv link.


(Pre-)Publications

  • Tilting Correspondences of Perfectoid Rings, October 2021, accepted to the Journal of the Ramanujan Mathematical Society

    We present an alternate proof of a vanishing result of étale cohomology on perfectoid rings due to Česnavičius.

  • Grothendieck--Serre over Smooth over Valuation Rings, in preparation.

    We show that a generically trivial torsor under a reductive group on a smooth algebra over a valuation ring of rank 1 is trivial.

  • Purity over Valuation Rings, in preparation.


Below, I list some of the seminars that I am/was co-organising.

Talks

  • Seminar CohoSing 02/22 - The Arc Topology
  • Seminar RéGA 12/2021 - Tilting Correspondences of Perfectoid Rings

I am a teacher at the Institut Universitaire Technologie (IUT), Cachan, France.

Teaching

Notes

Other activities

  • Since January 2021, I am building the website of
    École Parisienne d'Arithmétique et de Géométrie (EPAG).
    The goal is to centralise all relevant informations for PhD students in number theory and algebraic geometry in the Paris region.
  • I am a volunteer for the
    "Accueil International EGMathPS".
    Our objective is to help international students better integrate to Paris-Saclay and France in the context of their studies in mathematics (Master and PhD). So, if you are a Math student in Orsay/IHES/Evry/Versailles/Ecole Polytéchnique/ENS Paris-Saclay and you would like to join our discord channel, feel free to send me an email!
  • In the year 2020-2021, I was a grader of
    Marathon d'Orsay de Mathématiques
