For Eisenstein K3 surfaces, we construct invariants using equivariant
analytic torsions. The invariants give rise to automorphic forms on the coarse moduli\u00a0spaces of Eisenstein K3 surfaces, which are complex ball quotients. As applications,\u00a0we obtain reflective modular forms on some complex ball quotients, and we show\u00a0that some of the moduli spaces of Eisenstein K3 surfaces are quasi-affine. This is\u00a0joint work with Ken-Ichi Yoshikawa.<\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
