Dynamical Cobordism Conjecture: Solutions for End-of-the-World Branes

Ralph Blumenhagen, Christian Kneissl, Chuying Wang

We analyze finite size solutions for a generalized -dimensional Dudas-Mourad (DM) model featuring dynamical cobordism with neutral and charged end-of-the-world (ETW) defect bran…

Dimensional Reduction of Cobordism and K-theory

Ralph Blumenhagen, Niccolò Cribiori, Christian Kneissl +1

It has been proposed that cobordism and K-theory groups, which can be mathematically related in certain cases, are physically associated to generalised higher-form symmetries. As a…

Dynamical Cobordism of a Domain Wall and its Companion Defect 7-brane

Ralph Blumenhagen, Niccolò Cribiori, Christian Kneissl +1

Starting from an already known solution in the literature, we study the dynamical cobordism induced by the backreaction of a non-supersymmetric, positive tension domain wall in str…

Swampland Conjectures for an Almost Topological Gravity Theory

Rafael Álvarez-García, Ralph Blumenhagen, Christian Kneissl +2

We analyze AdS and dS swampland conjectures in a three-dimensional higher spin theory with self-interacting matter, which contains conformal gravity and is almost topological. A th…

De Sitter Quantum Breaking, Swampland Conjectures and Thermal Strings

Ralph Blumenhagen, Christian Kneissl, Andriana Makridou

We argue that under certain assumptions the quantum break time approach and the trans-Planckian censorship conjecture both lead to de Sitter swampland constraints of the same funct…
