The fundamental theorem of symmetric polynomials over rings is a classical result which states that every unital commutative ring elementary, i.e. we can express with elementary ones in unique way. does not extend directly to semirings, but do have analogous results for some special example, the tropical, extended and supertropical semirings. These all fall into larger class upper-bound In this...

Three methods for computing the upper bound when linear cuts are performed on the uncertainty set are described. One of them is based on the computation of spherical , one involves the construction of an implicit system to implement the linear constraints, and the other reformulates the problem into a higher dimensional one such that the standard upper bound computation can be used. The quality...
