“…Some of the earlier works on the subject include [25,37,38]. For more recent examples of differential cohomology applications in formal high-energy physics that are of some relevance to this work see [13,[39][40][41][42][43][44][45][46][47][48]. In this paper differential cohomology will be used to refine the notion of dimensional reduction (or KK-reduction) of supergravity theories, with the goal of providing a precise treatment of the effect of torsion cohomology classes in the compactification manifold.…”

“…This formalism is particularly useful to keep track of subtler aspects that emerge when we consider spacetimes with non-trivial topology (and in particular with torsional cycles). We refer the reader to [24,25,45,[60][61][62] for reviews aimed at physicists. We also highly recommend the textbook by Bär and Becker [63] for a pedagogical discussion of most of the results below.…”

We determine the d + 1 dimensional topological field theory, which encodes the higher-form symmetries and their 't Hooft anomalies for d-dimensional QFTs obtained by compactifying M-theory on a non-compact space X. The resulting theory, which we call the Symmetry TFT, or SymTFT for short, is derived by reducing the topological sector of 11d supergravity on the boundary ∂X of the space X. Central to this endeavour is a reformulation of supergravity in terms of differential cohomology, which allows the inclusion of torsion in cohomology of the space ∂X, which in turn gives rise to the background fields for discrete (in particular higher-form) symmetries. We apply this framework to 7d super-Yang Mills, where X = C 2 /Γ ADE , as well as the Sasaki-Einstein links of Calabi-Yau three-fold cones that give rise to 5d superconformal field theories. This M-theory analysis is complemented with a IIB 5-brane web approach, where we derive the SymTFTs from the asymptotics of the 5-brane webs. Our methods apply to both Lagrangian and non-Lagrangian theories, and allow for many generalisations.

“…where in our case A depends on the η-invariants for the gravitini and dilatini, as well as a slight extension of the anomaly theory of the chiral 4-form of type IIB supergravity developed in [21,[25][26][27]. Specifically, the anomaly theory relies on the existence of a canonical choice for the quadratic refinement of the pairing in differential cohomology, a feature which has only been shown to exist for Spin manifolds without a duality bundle turned on; in this paper, we assume that such a canonical choice exists for general Spin-GL + (2, Z) manifolds.…”

“…Still, to our knowledge, there has been no direct verification of this important feature (see however [19,20] which discuss a related anomaly). One obstacle in performing such a computation is that the evaluation of the partition function requires a detailed understanding of the self-dual field, and this has only recently been accomplished [21] (see also [22][23][24][25][26][27][28]).…”

Type IIB supergravity enjoys a discrete non-Abelian duality group, which has potential quantum anomalies. In this paper we explicitly compute these, and present the bordism group that controls them, modulo some physically motivated assumptions. Quite surprisingly, we find that they do not vanish, which naively would signal an inconsistency of F-theory. Remarkably, a subtle modification of the standard 10d Chern-Simons term cancels these anomalies, a fact which relies on the specific field content of type IIB supergravity. We also discover other ways to cancel this anomaly, via a topological analog of the Green-Schwarz mechanism. These alternative type IIB theories have the same low energy supergravity limit as ordinary type IIB, but a different spectrum of extended objects. They could either be part of the Swampland, or connect to the standard theory via domain walls.

“…Following the argument in[30,39], we assume that there is no half-integral contribution to the flux quantization condition as far as the setup in this paper in concerned.…”

We analyze the global symmetries and anomalies of 4d N = 1 field theories that arise from a stack of N M5-branes probing a class of flux backgrounds. These backgrounds consist of a resolved C 2 /Z k singularity fibered over a smooth Riemann surface of genus g ≥ 2, supported by a non-trivial G 4 -flux configuration labeled by a collection of 2(k − 1) flux quanta, {N i }. For k = 2, this setup defines a non-trivial superconformal field theory (SCFT) in the IR, which is holographically dual to an explicit AdS 5 solution first described by Gauntlett, Martelli, Sparks, and Waldram. The generalization to k ≥ 3 is hard to tackle directly within holography. Instead, in this paper we lay the groundwork for a systematic analysis of such a generalization by adopting anomaly inflow methods to identify continuous and discrete global symmetries of the 4d field theories. We also compute the 't Hooft anomalies for continuous symmetries at leading order in the limit of large N , N i .
