# Multiple series

From Encyclopedia of Mathematics

* $ s $-*
tuple series

An expression of the form

$$ \sum _ {m,n \dots p = 1 } ^ \infty u _ {m, n \dots p } , $$

consisting of the terms from a table $ \| u _ {m, n \dots p } \| $. Each term of the table is indexed by $ s \geq 2 $ indices $ m, n \dots p $, which run independently of each other over the set of natural numbers. The theory of multiple series is analogous to the theory of double series. See also Absolutely convergent series.
