In mathematics, a Picard modular surface, studied by , is a
complex surface
Complex commonly refers to:
* Complexity, the behaviour of a system whose components interact in multiple ways so possible interactions are difficult to describe
** Complex system, a system composed of many components which may interact with each ...
constructed as a quotient of the unit ball in C
2 by a
Picard modular group.
Picard modular surfaces are some of the simplest examples of
Shimura varieties and are sometimes used as a test case for the general theory of Shimura varieties.

In mathematics, a Hilbert modular surface or Hilbert–Blumenthal surface is an algebraic surface obtained by taking a quotient of a product of two copies of the upper half-plane by a Hilbert modular group. More generally, a Hilbert modular variet ...
