Combinatorics and Arithmetic
for Physics: special days,
28-29 Nov. 2022.

The meeting’s focus is about questions of discrete mathematics and number theory with an emphasis on computability. Problems are drawn mainly from theoretical physics : renormalisation, combinatorial physics, geometry, evolution equations (commutative and noncommutative) or related to its models, but not only. Computations, based on combinatorial structures (graphs,trees, words, automata, semirings, bases) or classical structures (operators, Hopf algebras, evolution equations, special functions, categories) are good candidates for computer-based implementation and experimentation.
