The metric has signature .

Greek letters from the middle of the alphabet denote coordinates in spacetime. Roman letters taken from the beginning of the alphabet denote coordinates on the worldsheet.

The metric is denoted . In the case where there is a metric of spacetime and a metric of the worldsheet, the worldsheet metric is denoted

A lower-case is the number of dimensions. An upper-class represents the number of spacial dimensions.
