Streszczenie
For a Legendre family of elliptic curves near the moduli space boundary, we study asymptotic behavior at a node of the relative Bergman kernel metric and show that its curvature form coincides with the Poincaré metric of $\mathbb C\setminus \{0, 1\}$. Four-term and three-term asymptotic expansion formulas near $0$ are obtained for this metric and its Kähler potential, respectively.
