I'm PhD Student at the University of YaoundÃ© I, Cameroon, under the direction of Pr Dossa Marcel.
My research focuses on the Existence of a Semi-global Solution of the Characteristic Cauchy Problem for the Einstein-Yang-Mills system field equations.
I am passionate about the geometry of Riemannian structure and more specifically, by:

- the formation and study of the singularities of these spaces; especially the geometry and dynamic of the black holes;
- the geometrization of differential varieties by means of a geometric flow; including: cobordism between connected varieties; the distribution of varieties around a model variety;
- the true nature of the curvature in mathematics; in particular, the link between Ricci curvature and the topology of a metrisable space.
- The geometry of the principal fiber bundle spaces; in particular: the study of the dynamics of the gauge group using the Cartan Moving Frame Method.
- The design of the minimal general framework for the
**riemannian** analysis (algebraic, geometric, random) of generalized variational differential systems.
- Natural (geo)metrizations of the transverse structure of a foliated manifold.

**Mathematician, Pure, Pure Immaculate. Without apologies...**

**God does not play dice ; in any way...**

**Geometry in the tradition of PoincarÃ©-Einstein: just visualize intensely and it will take shape...**

**Geometry in the tradition of Riemann-Klein-Lie-Chern-Thurston ...: Manufacturing highly sophisticated structures using the most elementary means...**

**This confidence that a child can have in his own lights, by relying on his faculties rather than taking things learned at school or read in books for granted, is a precious thing.**
**Alexander G. Grothendieck. The Spirit of Creativity.**

Any research on a geometry subject can be started from the work of any scientist; take any path whatsoever.
One fact, however, remains immutable: **at one point or another in our journey, we feel obliged to pass through the palace of His Imperial Majesty H. Weyl...**

**Unfortunately, we never know which problem is nice or which is ugly unless we solve it...
M. Gromov, Sign and Geometric meaning of curvature.**

My favorite field?
**Just solve, using geometry (in the very broad sense), a given mathematical problem.**

What is Riemann-Cartan Geometry? It's just an **expression of blind faith in A. G. Grothendieck's "pinned butterfly" principle under the leadership of the "high priest" V. I. Arnold.**

It will be difficult if not **impossible** to have many others A. G. Grothendieck.
This for the simple reason that young mathematicians are asked **to be both A. G. Grothendieck and J. A. DieudonnÃ© and above all, I.H.E.S!!!**
Which is simply impossible!!!
