Irregular cusps of ball quotients

چکیده
We study the branch divisors on boundary of canonical toroidal compactification ball quotients. show a criterion, low slope cusp form trick, for proving that quotients are general type. Moreover, we classify when irregular cusps exist in case discriminant kernel and construct concrete examples some arithmetic subgroups. As another direction study, complex is embedded into Hermitian symmetric domain type IV, determine regular or map to studied by Ma.

Hurwitz ball quotients
We consider the analogue of Hurwitz curves, smooth projective curves C of genus g ≥ 2 that realize equality in the Hurwitz bound |Aut(C)| ≤ 84(g − 1), to smooth compact quotients S of the unit ball in C. When S is arithmetic, we show that |Aut(S)| ≤ 288e(S), where e(S) is the (topological) Euler characteristic, and in the case of equality show that S is a regular cover of a particular Deligne–M...
متن کاملForgetful Maps between Deligne-mostow Ball Quotients
We study forgetful maps between Deligne-Mostow moduli spaces of weighted points on P, and classify the forgetful maps that extend to a map of orbifolds between the stable completions. The cases where this happens include the Livné fibrations and the Mostow/Toledo maps between complex hyperbolic surfaces. They also include a retraction of a 3-dimensional ball quotient onto one of its 1-dimension...
متن کاملIrregular diffusion in the bouncing ball billiard
We call a system bouncing ball billiard if it consists of a particle that is subject to a constant vertical force and bounces inelastically on a one-dimensional vibrating periodically corrugated floor. Here we choose circular scatterers that are very shallow, hence this billiard is a deterministic diffusive version of the well-known bouncing ball problem on a flat vibrating plate. Computer simu...
متن کاملCompact Arithmetic Quotients of the Complex 2-ball and a Conjecture of Lang
Let H C be the 2-dimensional complex hyperbolic space, represented by the unit ball in C equipped with the Bergmann metric of constant holomorphic sectional curvature −1, on which the Lie group U(2, 1) acts in a natural way. Let Γ be a cocompact arithmetic discrete subgroup of U(2, 1). By the Baily-Borel theorem the quotient XΓ := Γ\H 2 C has a structure of a normal, projective surface, in fact...
متن کاملArithmetic Quotients of the Complex Ball and a Conjecture of Lang
For any integer n > 1, let Hn C be the n-dimensional complex hyperbolic space, represented by the unit ball in Cn equipped with the Bergman metric of constant holomorphic sectional curvature −4/(n+ 1), on which the real Lie group U(n, 1) acts in a natural way. Given a lattice Γ in U(n, 1), we consider the quotient YΓ := Γ\Hn C. Let M be a CM quadratic extension of a totally real number field F ...
