**2. Conference on Algebraic Geometry, Representation theory and Mathematical Physics**

**Location**:

Harvard CMSA, 20 Garden Street, Cambridge, MA, April 29, 2019 to May 1, 2019.

This conference discussed recent advancements in algebraic geometry, representation theory and mathematical physics around Homological Mirror Symmetry conjecture announced by Maxim Kontsevich in 1994.

**3. Conference on Moduli and Invariants**

**Location**:

The Casa Matemática Oaxaca (CMO), November 17, 2019 to November 22, 2019.
