Non associative magnetic translations from parallel transport in projective Hilbert bundles

Jouko Mickelsson, Michael Murray

The non-associativity of translations in a quantum system with magnetic field background has received renewed interest in association with topologically trivial gerbes over $\mathb…

JNR Monopoles

Michael K. Murray, Paul Norbury

We review the theory of JNR, mass 1/2 hyperbolic monopoles in particular their spectral curves and rational maps. These are used to establish conditions for a spectral curve to be…

The Weyl map and bundle gerbes

Kimberly E. Becker, Michael K. Murray, Daniel Stevenson

We introduce the notion of a general cup product bundle gerbe and use it to define the Weyl bundle gerbe on T x SU(n)/T. The Weyl map from T x SU(n)/T to SU(n) is then used to show…

Sign choices for orientifolds

Pedram Hekmati, Michael K. Murray, Richard J. Szabo +1

We analyse the problem of assigning sign choices to O-planes in orientifolds of type II string theory. We show that there exists a sequence of invariant -gerbes with ,…

Real bundle gerbes, orientifolds and twisted KR-homology

Pedram Hekmati, Michael K. Murray, Richard J. Szabo +1

We consider Real bundle gerbes on manifolds equipped with an involution and prove that they are classified by their Real Dixmier-Douady class in Grothendieck's equivariant sheaf co…

Equivariant bundle gerbes

Michael K. Murray, David Michael Roberts, Danny Stevenson +1

We develop the theory of simplicial extensions for bundle gerbes and their characteristic classes with a view towards studying descent problems and equivariance for bundle gerbes.…
