Bertrand Teguia Tabuguia, Ph.D.

Intro. Hi, welcome!

Until recently, I was a Research Associate under the mentorship of James Worrell at the University of Oxford, UK. Before that, I held a short Postdoctoral position in the group of Joël Ouaknine at the Max Planck Institute (MPI) for Software Systems, Saarbrücken, Germany. Previously, I was a Postdoctoral Researcher in the Nonlinear Algebra group of Bernd Sturmfels at MPI for Mathematics in the Sciences, Leipzig. I took a partial break from December 2025 to April 2026.

Research Interests: my research interests combine Symbolic Computation, Differential/Difference Algebra, Math Software Development, Algorithmic Number Theory, Algebraic Geometry, and their applications in other scientific areas.

Associate Editor for Maple Transactions.

Out for presentations at workshops and conferences:

• Subsequences and rational recursions
  for solutions of polynomial difference equations.
  May 2026. Supplementary files: Example. Worksheet.
  Based on revisions of Preprint 2 below.
  Accepted for presentation at CASC 2026.
  
  
• Nonlinear differential guessing in practice. 
  May 2026. Links: Software. Examples. Worksheet.
  Builds on Preprint 1 below.
  Accepted for software presentation at ISSAC 2026.

Recent preprints:

1. D-algebraic guessing. (submitted)
   
   This is about finding differential and difference equations satisfied by a sequence or its generating function from its first few terms. It is proved in the last section that the sequence of primes is not D-algebraic.
   
   
2. Computing with D-algebraic sequences. (under revision)
   
   A study of sequences defined by polynomial difference equations and some of their subclasses.
