The Twofold Way of Super Holonomy
There are two different notions of holonomy in supergeometry, the supergroup
introduced by Galaev and our functorial approach motivated by super Wilson
loops. Either theory comes with its own version of invariance of vectors and
subspaces under holonomy. By our first main result, the Twofold Theorem, these
definitions are equivalent. Our proof is based on the Comparison Theorem, our
second main result, which characterises Galaev's holonomy algebra as an algebra
of coefficients, building on previous results. As an application, we generalise
some of Galaev's results to S-points, utilising the holonomy functor. We
obtain, in particular, a de Rham-Wu decomposition theorem for semi-Riemannian
S-supermanifolds.Comment: 25 pages, in this second version many improvements mainly thanks to
suggestions by Alexander Alldridge and Dominik Ostermay
Vertex Operators of Super Wilson Loops
We study the supersymmetric Wilson loop as introduced by Caron-Huot, which
attaches to lightlike polygons certain edge and vertex operators, whose shape
is determined by supersymmetry constraints. We state explicit formulas for the
vertex operators to all orders in the Gra{\ss}mann expansion, thus filling a
gap in the literature. This is achieved by deriving a recursion formula out of
the supersymmetry constraints.Comment: 11 page
