TASI Lectures on the Mathematics of String Dualities
Niklas Garner, Natalie M. Paquette
In these lecture proceedings, we describe some of the fundamental mathematical concepts that underlie supersymmetric string theory and field theory, and their role in describing an…

Mirror symmetry and line operators
Tudor Dimofte, Niklas Garner, Michael Geracie +1
We study half-BPS line operators in 3d N=4 gauge theories, focusing in particular on the algebras of local operators at their junctions. It is known that there are two basic types…

Coulomb Branches of Star-Shaped Quivers
Tudor Dimofte, Niklas Garner
We study the Coulomb branches of 3d N=4 `star-shaped' quiver gauge theories and their deformation quantizations, by applying algebraic techniques that have been developed in the ma…
