Title: Generic representations of orthogonal groups: projective functors in the category F<sub>quad</sub>
Abstract: We continue the study of the category of functors ${\cal F}_{{\rm quad}}$, associated to ${\mathbb F}_2$-vector spaces equipped with a nondegenerate quadratic form, initiated in J. Pure Appl. Algebra 212 (2008) and Algebr. Geom. Topology 7 (2007). We def
