Analytic plane
complex-analytic plane
A non-empty set of points in the complex vector space \mathbf C ^ {n} that satisfies a system of equations
\sum _ {i = 1 } ^ { n } a _ {i j } z _ {i} = b _ {j} , \ j = 1 \dots k ; \ a _ {i j } , b _ {j} \in \mathbf C ;
\mathop{\rm rank} \| a _ {i j } \| = k < n .
The number k is called the complex codimension, while n - k is called the complex dimension of the analytic plane. The real dimension of the analytic plane equals 2 (n - k ) and is even, but not all even-dimensional real planes in \mathbf R ^ {2n} = \mathbf C ^ {n} are analytic planes. Complex one-dimensional analytic planes are sometimes called complex, or analytic, straight lines. See also Analytic surface.
