A missing link: Brane networks and the Cobordism Conjecture
Markus Dierigl, Ignacio Ruiz
The absence of global symmetries in a quantum gravity theory often requires the introduction of (new) symmetry-breaking defects, which appear as singular objects in the low-energy…
Bounds on Discrete Gauge Symmetries in Supergravity
Zihni Kaan Baykara, Markus Dierigl, Hee-Cheol Kim +2
We place bounds on the order of enhanced discrete gauge symmetries that act on massless fields and thus arise at subloci of the moduli space in supergravity theories. We focus on s…
Modified Abelian Gauge Theories
Markus Dierigl, Ruben Minasian, DuÅ¡an NoviÄiÄ
The topological properties of field configurations in gauge theory contain important data about the (generalized) global symmetries of the theory as well as potential inconsistenci…
Exploring Pintopia: Reflection Branes, Bordisms, and U-Dualities
Vivek Chakrabhavi, Arun Debray, Markus Dierigl +1
The U-dualities of maximally supersymmetric non-chiral supergravity (SUGRA) theories lead to strong constraints on the non-perturbative structure of quantum gravity. In this paper…
Cobordism Utopia: U-Dualities, Bordisms, and the Swampland
Noah Braeger, Arun Debray, Markus Dierigl +2
The U-dualities of maximally supersymmetric supergravity theories lead to celebrated non-perturbative constraints on the structure of quantum gravity. They can also lead to the pre…
(Quadratically) Refined Discrete Anomaly Cancellation
Markus Dierigl, Michelangelo Tartaglia
In this work we study the cancellation of non-perturbative anomalies of gravitational theories with gauge group in six dimensions. These subtle anomalies require a c…
