Abstract
Maximal doubly-even self-orthogonal binary linear codes correspond to the maximal elementary abelian 2-groups of the spinor group Spin(n). We will describe the correspondence and discuss various techniques from the algebraic topology of Spin(n) which may be useful in studying self-orthogonal codes. In particular, Quillen’s results in equivariant cohomology theory coupled with some Morse theory may allow one to address certain questions on the minimum weight of doubly-even self-orthogonal codes.
