A three-block higher-rank deformed Hermitian--Yang--Mills correspondence on

Yuqi Li, Hao-Yu Sun

We study the invariant rank-four deformed Hermitian--Yang--Mills equation associated with the chain over ,…

Cusp restrictions and Bunke--Naumann invariants with level structure

Yuqi Li, Hao-Yu Sun

Restriction to the full cusp divisor of a modular curve defines a secondary invariant whose rational indeterminacy comes from a single global modular form. For every integral weakl…

The hyperbolic class and vanishing laws in a TMF-valued four-manifold invariant

Yuqi Li, Hao-Yu Sun

Under explicit hypotheses on the spectral Looijenga construction, we compute the hyperbolic-plane value of the zero-section invariant of Gukov, Krushkal, Meier, and Pei in periodic…

Left-handed string and CHY amplitude at one loop

Yuqi Li, Warren Siegel

We propose a generalized left-handed (chiral) gauge choice for the genus one Riemann surface, realized through a singular gauge transformation of worldsheet coordinates. The transf…

Towards -finiteness: -deformed open string amplitude

Yuqi Li, Hao-Yu Sun

Revisiting the Coon amplitude, a deformation of the Veneziano amplitude with a logarithmic generalization of linear Regge trajectories, we scrutinize its potential origins in a wor…

Remarks on the critical dimension of left-handed string and its quasiconformal nature

Yuqi Li, Warren Siegel

The chiral string without a singular gauge limit is argued to have the same critical dimension as its corresponding conventional closed string. Thus, its central charge would be th…

Chiral Superstring and CHY Amplitude

Yuqi Li, Warren Siegel

We calculate the chiral string amplitude in pure spinor formalism and take four point amplitude as an example. The method could be easily generalized to point amplitude by comp…
