| contents | In this paper, we provide a lower bound for the Cheeger constant and the spectral gap for random complex curves in $\C P^2$. The complex curve is endowed with the restriction of the ambient Fubini-Study metric, and the probability measure is the Gaussian measure induced by the $\mathscr{L}^2$-Hermitian product on the space of complex homogeneous polynomialsof degree $d$ in $3$ variables. The proof relies on our previous bounds for the systole and the curvature of random complex curves, together with an isoperimetric inequality for small ovals on complex curves. More generally, we establish such lower bounds for random complex curves within complex projective manifolds. |
