Filtering cohomology of ordinary and Lagrangian Grassmannians
The 2020 Polymath Jr. REU "q-binomials, the Grassmannian group", : +31
This paper studies, for a positive integer , the subalgebra of the cohomology ring of the complex Grassmannians generated by the elements of degree at most . We build in two…
Fusion 2-categories with no line operators are grouplike
Theo Johnson-Freyd, Matthew Yu
We show that if is a fusion -category in which the endomorphism category of the unit object is or , then the indecomposable objects of $\math…
Symmetries and Anomalies of (1+1)d Theories: 2-groups and Symmetry Fractionalization
Matthew Yu
We investigate the interactions of discrete zero-form and one-form global symmetries in (1+1)d theories. Focus is put on the interactions that the symmetries can have on each other…
T-Duality in Nonrelativistic Open String Theory
Jaume Gomis, Ziqi Yan, Matthew Yu
Nonrelativistic open string theory is defined by a worldsheet theory that produces a Galilean invariant string spectrum and is described at low energies by a nonrelativistic Yang-M…
Nonrelativistic Open String and Yang-Mills Theory
Jaume Gomis, Ziqi Yan, Matthew Yu
The classical and quantum worldsheet theory describing nonrelativistic open string theory in an arbitrary nonrelativistic open and closed string background is constructed. We show…
