Quantum -invariants via Quot schemes I
Shubham Sinha, Ming Zhang
We study the virtual Euler characteristics of sheaves over Quot schemes of curves, establishing that these invariants fit into a topological quantum field theory (TQFT) valued in $…

Quantum spectrum and Gamma structures for quasi-homogeneous polynomials of general type
Yefeng Shen, Ming Zhang
Let be a quasi-homogeneous polynomial of general type and be the cyclic symmetry group of generated by the exponential grading element . We study the quantum spect…
