We present a construction of a 2-Hilbert space of sections of a bundle gerbe, a suitable candidate for a prequantum 2-Hilbert space in higher geometric quantisation. We introduce a direct sum on the morphism categories in the 2-category of bundle gerbes and show that these categories are cartesian monoidal and abelian. Endomorphisms of the trivial bundle gerbe, or higher functions, carry the structure of a rig-category, which acts on generic morphism categories of bundle gerbes. We continue by… 

Smooth 2-Group Extensions and Symmetries of Bundle Gerbes

We study bundle gerbes on manifolds M that carry an action of a connected Lie group G. We show that these data give rise to a smooth 2-group extension of G by the smooth 2-group of hermitean line

Gerbes in Geometry, Field Theory, and Quantisation

Abstract This is a mostly self-contained survey article about bundle gerbes and some of their recent applications in geometry, field theory, and quantisation. We cover the definition of bundle gerbes

Principal ∞-Bundles and Smooth String Group Models

We provide a general, homotopy-theoretic definition of string group models within an ∞-category of smooth spaces, and we present new smooth models for the string group. Here, a smooth space is a

Transgression of D-branes

Closed strings can be seen either as one-dimensional objects in a target space or as points in the free loop space. Correspondingly, a B-field can be seen either as a connection on a gerbe over the

Smooth functorial field theories from B-fields and D-branes

In the Lagrangian approach to 2-dimensional sigma models, B-fields and D-branes contribute topological terms to the action of worldsheets of both open and closed strings. We show that these terms

Principal $$\infty $$-bundles and smooth string group models

We provide a general, homotopy-theoretic definition of string group models within an $$\infty $$ ∞ -category of smooth spaces and present new smooth models for the string group. Here, a smooth

Current Groups and the Hamiltonian Anomaly

Gauge symmetry invariance is an indispensable aspect of the eld-theoretic models in classical and quantum physics. Geometrically this symmetry is often modelled with current groups and current

Geometry and 2-Hilbert space for nonassociative magnetic translations

We suggest a geometric approach to quantisation of the twisted Poisson structure underlying the dynamics of charged particles in fields of generic smooth distributions of magnetic charge, and dually



The 2-Hilbert Space of a Prequantum Bundle Gerbe

We construct a prequantum 2-Hilbert space for any line bundle gerbe whose Dixmier-Douady class is torsion. Analogously to usual prequantisation, this 2-Hilbert space has the category of sections of

Fluxes, bundle gerbes and 2-Hilbert spaces

We elaborate on the construction of a prequantum 2-Hilbert space from a bundle gerbe over a 2-plectic manifold, providing the first steps in a programme of higher geometric quantisation of closed

Algebraic Structures for Bundle Gerbes and the Wess-Zumino Term in Conformal Field Theory

Surface holonomy of connections on abelian gerbes has essentially improved the geometric description of Wess-Zumino-Witten models. The theory of these connections also provides a possibility to

Principal ∞-bundles - General theory

The theory of principal bundles makes sense in any ∞-topos, such as the ∞-topos of topological, of smooth, or of otherwise geometric ∞-groupoids/∞-stacks, and more generally in slices of these. It

T-Duality via Gerby Geometry and Reductions

We consider topological T-duality of torus bundles equipped with S^{1}-gerbes. We show how a geometry on the gerbe determines a reduction of its band to the subsheaf of S^{1}-valued functions which

Higher-Dimensional Algebra II. 2-Hilbert Spaces☆

Abstract A 2-Hilbert space is a category with structures and properties analogous to those of a Hilbert space. More precisely, we define a 2-Hilbert space to be an Abelian category enriched over Hilb

Principal ∞-bundles – Presentations

We discuss two aspects of the presentation of the theory of principal ∞-bundles in an ∞-topos, introduced in [NSSa], in terms of categories of simplicial (pre)sheaves. First we show that over a

Cohomological quantization of local prequantum boundary eld theory

We discuss how local prequantum field theories with boundaries can be described in terms of nfold correspondence diagrams in the ∞-topos of smooth stacks equipped with higher circle bundles. This

Bundle Gerbes for Chern-Simons and Wess-Zumino-Witten Theories

We develop the theory of Chern-Simons bundle 2-gerbes and multiplicative bundle gerbes associated to any principal G-bundle with connection and a class in H4(BG, ℤ) for a compact semi-simple Lie

Geometric quantization of Chern-Simons gauge theory

We present a new construction of the quantum Hubert space of ChernSimons gauge theory using methods which are natural from the threedimensional point of view. To show that the quantum Hubert space
