Abstract

Our project is concerned with algebraic & topological properties of configuration spaces & braid groups, notably those of the disc D^2, the sphere S^2& the projective plane RP^2, some generalizations, such as orbit configuration spaces, & the relations of these braid groups with the classical crystallographic groups. The braid groups & their generalizations have attracted much attention, partly due to the fact that these groups arise in various contexts (topology, knot theory, algebra) Our proposal focusses on 3 different aspects: the homotopy fibres of inclusions of the configuration spaces of S ^2 & RP^2 in the Cartesian product, and orbit configuration spaces; the conjugacy classes of the finite subgroups of the braid groups of RP^2; & the relations between the braid groups of D^2, S^2, RP^2 and crystallographic groups. We will study these problems using algebra, algebraic topology, topology geometry. The results should have consequences for the associated mapping class groups. (AU)
