Taxonomy of Instanton Corrections in Infinite Distance Limits
Manuel Artime, Ralph Blumenhagen, Panagiotis Leivadaros
Using the BPS-protected higher derivative -term as an exactly solvable example, we analyze which instanton corrections are generated by a one-loop Schwinger integral over the…
The Emergent M-theory Limit
Ralph Blumenhagen, Niccolò Cribiori, Aleksandar Gligovic +1
It has been recently proposed that at each infinite distance limit in the moduli space of quantum gravity a perturbative description emerges with fundamental degrees of freedom giv…
Demystifying the Emergence Proposal
Ralph Blumenhagen, Niccolò Cribiori, Aleksandar Gligovic +1
We revisit the Emergence Proposal in the vector multiplet moduli space of type IIA N=2 supersymmetric string vacua in four dimensions, for which the string tree-level prepotential…
The Emergence Proposal and the Emergent String
Ralph Blumenhagen, Aleksandar Gligovic, Antonia Paraskevopoulou
We explore the Emergence Proposal for the moduli metric and the gauge couplings in a concrete model with 7 saxionic and 7 axionic moduli fields, namely the compactification of the…
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…
