On the Kaehler metrics over ${mathrm{Sym}^{d}(X)$
  Let $X$ be a compact connected Riemann surface of genus $g$, with $g \geq 2$. For each $d <\eta(X)$, where $\eta(X)$ is the gonality of $X$, the symmetric product $\text{Sym}^d(X)$ embeds into $\text{Pic}^d(X)$ by sending an effective divisor of degree $d$ to the corresponding holomorphic line bundle. Therefore, the restriction of the flat K\"ahler metric on $\text{Pic}^d(X)$ is a K\"ahler metric on $\text{Sym}^d(X)$. We investigate this K\"ahler metric on $\text{Sym}^d(X)$. In particular, we estimate it's Bergman kernel. We also prove that any holomorphic automorphism of $\text{Sym}^d(X)$ is an isometry.
