Part 3 4d gauge theory and 2d CFT from 6d point of view

The notion of free product with amalgamation of groupoids in [16] strongly influenced Ronnie Brown to introduce in [5] the fundamental groupoid on a set of base points, and so to give

The torsion free generalized connection is determined and its coefficients are obtained under condition that the metric structure is parallel or recurrent.. The Einstein-Yang

What the Vasiliev theory of higher spins does is basically that it extends the gauge algebra so(3, 2) to the higher spin algebra hso(3, 2) (and correspondingly in other dimensions

We show some symmetry relations among the correlation functions of the in- tegrable higher-spin XXX and XXZ spin chains, where we explicitly evaluate the multiple integrals

In [BH] it was shown that the singular orbits of the cohomogeneity one actions on the Kervaire spheres have codimension 2 and 2n, and that they do not admit a metric with

In analogy with Aubin’s theorem for manifolds with quasi-positive Ricci curvature one can use the Ricci flow to show that any manifold with quasi-positive scalar curvature or

Definition An embeddable tiled surface is a tiled surface which is actually achieved as the graph of singular leaves of some embedded orientable surface with closed braid
