UNDECIDABILITY AND THE DEVELOPABILITY OF PERMUTOIDS AND RIGID PSEUDOGROUPS
Forum of Mathematics, Sigma, 2017 A permutoid is a set of partial permutations that contains the identity and is such that partial compositions, when defined, have at most one extension in the set.

Ramsey numbers of cycles versus general graphs
Forum of Mathematics, Sigma, 2023 The Ramsey number $R(F,H)$ is the minimum number N such that any N-vertex graph either contains a copy of F or its complement contains H. Burr in 1981 proved a pleasingly general result that, for any graph H, provided n is sufficiently large, a ...

Box graphs and resolutions II: From Coulomb phases to fiber faces
Nuclear Physics B, 2016 Box graphs, or equivalently Coulomb phases of three-dimensional N=2 supersymmetric gauge theories with matter, give a succinct, comprehensive and elegant characterization of crepant resolutions of singular elliptically fibered varieties. Furthermore, the

Geometry of polycrystals and microstructure
MATEC Web of Conferences, 2015 We investigate the geometry of polycrystals, showing that for polycrystals formed of convex grains the interior grains are polyhedral, while for polycrystals with general grain geometry the set of triple points is small.

A Comparative Study of Optimal Energy Management Strategies for Energy Storage with Stochastic Loads
Energies, 2020 This paper aims to present the significance of predicting stochastic loads to improve the performance of a low voltage (LV) network with an energy storage system (ESS) by employing several optimal energy controllers.

A geometric dual of c-extremization
Journal of High Energy Physics, 2019 We consider supersymmetric AdS3 × Y 7 and AdS2 × Y 9 solutions of type IIB and D = 11 supergravity, respectively, that are holographically dual to SCFTs with (0, 2) supersymmetry in two dimensions and N $$ \mathcal{N} $$ = 2 supersymmetry in one ...

Supertwistor description of ambitwistor strings
Journal of High Energy Physics, 2020 A new ambitwistor string is constructed based on a ten-dimensional super-twistor model for the massless superparticle. Although covariant quantization is complicated by reducibility issues, a light-cone gauge analysis can be easily performed.
