Sigma in mathematics
Sigma is the eighteenth letter of the Greek alphabet. In the system of Greek numerals, it has a value of 200. In general mathematics, uppercase Σ is used as an operator for summation. When used at the end of a letter-case word (one that does not use all caps), the final form (ς) is used. In Ὀδυσσεύς (Odysseus), for example, the two lowercase sigmas (σ) in the center of the name are distinct from the word-final sigma (ς) at the end.

The definition of a sigma-field requires that we have a sample space S along with a collection of subsets of S. This collection of subsets is a sigma-field if the following conditions are met: If the subset A is in the sigma-field, then so is its complement AC. If An are countably infinitely many subsets from the sigma-field, then ...
