Dr. Robert Coulter

 

 

 

 

 

Teaching (Fall semester of academic year 2025/2026):

  • Math845 – Algebra Two.

Research Interests:

    • Finite fields and applications.
    • Polynomials over finite fields, particularly their roles in projective geometry, information security and combinatorics.
    • Construction of cryptographically useful functions such as APN functions, planar functions, and PPs with low differential uniformity.
    • Construction and classification of Cartesian groups, quasifields and semifields.
    • Automorphism groups of combinatorial and algebraic objects, and the interrelated problems of isotopy of algebraic objects and isomorphism of projective planes.
    • Projective planes, especially planes of small order, the Prime Power Conjecture and the Prime = Desargues Conjecture.
