A new construction of Virasoro blocks
Qianyu Hao, Andrew Neitzke
We introduce a nonabelianization map for conformal blocks, which relates Virasoro blocks on a Riemann surface to Heisenberg blocks on a branched double cover $\widetilde{…
Exact WKB of solutions by Borel summation and open TBA
Qianyu Hao
In this paper, we study the exact WKB methods for solutions of the Schrödinger equations corresponding to quantum Seiberg-Witten curves in 4d theories with surface…
Connecting topological strings and spectral theory via non-autonomous Toda equations
Pavlo Gavrylenko, Alba Grassi, Qianyu Hao
We consider the Topological String/Spectral theory duality on toric Calabi-Yau threefolds obtained from the resolution of the cone over the singularity. Assuming Kyiv for…
On quivers, spectral networks and black holes
Paolo Arnaudo, Alba Grassi, Qianyu Hao
It was recently found that connection coefficients of the Heun equation can be derived in closed form using crossing symmetry in two-dimensional Liouville theory via the Nekrasov-S…
