Yuri Ximenes Martins

I am a PhD student at Departament of Mathematics of Universidade Federal de Minas Gerais (UFMG), Brazil.

I am mainly interested in applying (higher) categorical theory to Physics and Mathematics, and also in some aspects of differential geometry. Previously I was involved with mathematical aspects of Astrophysics.

The best way to contact me is through

I am co-founder of a research group on mathematical-physics and categorification called Math-Phys-Cat Group.


Papers and Preprints

On higher category theory and physics in view of Hilbert's sixth problem:

On obstructions to realize gravity (as Einstein–Hilbert–Palatini theories) in geometries other than Lorentzian and Riemannian:

On the classification problem of extensions of Yang-Mills-Type theories:

On the axiomatization problem of Astrophysics:

On a program attempting to get existence and multiplicity results for geometric objects on C kC^k-manifolds fulfilling arbitrarily given regularity conditions.

On an axiomatization proposal to the notion of strong emergence between Lagrangian field theories:

A generalized and simplified version of the above work:

On a functorial extension of Feynman rules from Feynman graphs to structured hypergraphs.

Textbooks and Lecture Notes

On an introduction to (algebraic) topology and differential geometry aiming the study of general spherically symmetric black holes (in Brazilian portuguese):

On an introduction to abstract homotopy theory by means of model categories and (infinity,1)-categories (in Brazilian Portuguese):

On the role of higher category theory in the foundations of physics:

  • Towards an Approach to Hilbert’s Sixth Problem. I SEMAT, UFLA, 2017. Notes available here. See also (hal:02909681)

On a vertical categorification of Lie algebras (called Lie algebroidal categories) and a connection with Lie algebroids. A priori the Lie algebroidal categories differs from Lie 2-algebras of Baez-Crans, but further investigations are needed.

Currently I am (co)advising three master students (joint Rodney Josué Biezuner). For past advising, see here.

  • Mayk Alves de Andrade, Modal Homotopy Type Theory on the Foundations of Physics, started 2019/2

  • Daniel de Souza Plácido Teixeira, Higher Quantization, started 2020/1

  • Pedro Brunialti Lima de Andrade, Abstract Stable Homotopy Theory, started 2020/1
