On Motivic and Arithmetic Refinements of Donaldson-Thomas invariants
Felipe Espreafico, Johannes Walcher
In recent years, a version of enumerative geometry over arbitrary fields has been developed and studied by Kass-Wickelgren, Levine, and others, in which the counts obtained are not…
Fluxes, Vacua, and Tadpoles meet Landau-Ginzburg and Fermat
Katrin Becker, Eduardo Gonzalo, Johannes Walcher +1
Type IIB flux vacua based on Landau-Ginzburg models without Kähler deformations provide fully-controlled insights into the non-geometric and strongly-coupled string landscape. We s…
Six-dimensional supermultiplets from bundles on projective spaces
Fabian Hahner, Simone Noja, Ingmar Saberi +1
The projective variety of square-zero elements in the six-dimensional minimal supersymmetry algebra is isomorphic to . We use this fact, together…
A Local Wheeler-DeWitt Measure for the String Landscape
Bjoern Hassfeld, Arthur Hebecker, Manfred Salmhofer +2
According to the `Cosmological Central Dogma', de Sitter space can be viewed as a quantum mechanical system with a finite number of degrees of freedom, set by the horizon area. We…
A-model Implications of Extended Mirror Symmetry
Lukas Hahn, Johannes Walcher
Associativity of the quantum product ensures flatness of the Dubrovin connection and is the basis for Hodge-theoretic mirror symmetry of Calabi-Yau threefolds. We use ring and modu…
Nilpotence varieties
Richard Eager, Ingmar Saberi, Johannes Walcher
We consider algebraic varieties canonically associated to any Lie superalgebra, and study them in detail for super-Poincaré algebras of physical interest. They are the locus of nil…
