In the seminar of 2024, we try to cover 1. Review of BRST and BV 2. AKSZ theory with derived symplectic geometry 3. Review of string theory with branes and super symmetry(possibly super gravity also) 4. Vertex operators and W algebras in string theory 5. BCOV theory with mirror symmetry 6. Quantum Black holes 7. Categorical quantum field theory 8. Feynman integrals with tropical geometry
