摘要:The $A+B$ theory was shown to be an invariance for projective conifold transitions of smooth Calabi—Yau 3-folds $X\nearrow Y$ by Lee, Lin, and Wang, where the $A$ theory is the GW theory and the $B$ theory is  the variation of Hodge structures. In this talk, I will give an introduction to the theory, especially focusing on the part $A(Y)+B(Y)\Rightarrow B(X)$.Reference: Towards A + B theory in conifold transitions for Calabi—Yau threefolds,to appear in J.
