Relative De Rham cohomology in diffeological spaces
Published 10 Jun 2023 in math.AT | (2306.06478v4)
Abstract: We define two different versions of the relative De Rham cohomology groups of a diffeological space. Additionally, we study a variant of the Mayer-Vietoris sequence and discuss the existence of a relative cup product. Our approach is categorical, replacing open coverings with generating families and unions and intersections with pull-back and join constructions.
