Nous présentons un panorama des théorèmes de comparaison entre les cohomologies de De Rham algébrique et analytique à coefficients dans des connections algébriques. Ces théorèmes ont joué un rôle ...

A mathematical proof is a sequence of statements that follow on logically from each other that shows that something is always true. Using letters to stand for numbers means that we can make statements ...

The interplay between algebraic structures and orthogonal polynomials has emerged as a central theme in contemporary mathematics and theoretical physics. At its core, this research area explores how ...

Educational Studies in Mathematics, Vol. 93, No. 3 (November 2016), pp. 333-361 (29 pages) Algebra has been explicit in many school curriculum programs from the early years but there are competing ...

Algebra can be demystified with the right approach. Transforming word problems into mathematical expressions is crucial, alongside using formula sheets and colour-coding equations for clarity.
