{wiki=Siegel_upper_half-space}
The Siegel upper half-space, typically denoted as \\( \\mathcal\{H\}_g \\), is a concept from several complex variables and algebraic geometry. It is a generalization of the upper half-plane concept found in one complex variable and is an important object in the study of several complex variables, algebraic curves, and arithmetic geometry.
