(mathematics)
An extended real-valued function m defined on a sigma algebra of subsets of a set S such that (1) the value of m on the empty set is 0, (2) the value of m on a countable union of disjoint sets is the sum of its values on each set, and (3) m assumes at most one of the values + ∞ and - ∞.

Also it can be observed that for a fixed value of RP, the value of '-[theta](0)' for negative variation of viscosity ([[gamma].sub.[mu]] = -0.5) is always higher than the value of '-[theta]'(0)' for constant viscosity ([[gamma].sub.[mu]] = 0) and the value of '-[theta](0)' for positive variation of viscosity ([[gamma].sub.[mu]] = 0.5) is always less than for constant viscosity ([[gamma].sub.[mu]] = 0).
