In the following paper , in page 621 in 1 , I am trying to understand the proof of part 1.

In the proof of part 1 of inequality the authors first use of logarithmic transformation due to Kodaira. After they say

"Therefore $ω_{SF}$ is a smooth family of Ricci-flat metrics over $B$". I can not see this fact.

In the first part of proof they define $\tilde Y=\mathbb C\times \tilde B/L$, BUT I think we must define $\tilde Y=\mathbb C\times B/L$.

In final The proof is not clear for me
