If the Sigma does not mean the sum operator, its meaning must be explained in the context. Seeing the formula only, it is impossible to guess its meaning. Please examine the surrounding text or the previous equations.

Some terms later a lower case sigma occurres with equivalent indices. So perhaps it is simply a typo confusing upper and lower case.
