....returns a formula in # Par ( m) Corollary 2.4. 3 If # m) then D(x, #) is in # Par ( m) An algorithm to solve the problem of the quantifier elimination of real variables with general formulae in # P ( m) is given in [86] This is a generalization of Sturm s algorithm (see [27]) Sturm s algorithm calculates the number of changes of positivity (and so also the number of roots) of a polynomial in an interval. We call D # (x, the formula resulting by the algorithm defined in [86] # ; with Del IR (x, #) we denote the formula # ## where # ## is the formula D(x, #) if ....

....to a formula ) where # # is simple. It is decidable whether a formula ) where # # is simple, is satisfiable. This derives from the fact that if a n k . a 1 k a 0 is a polynomial, then the roots are in the interval [ M,M ] where M = max( an , a . a ) an (see [27]) # 2.5.1 Discussion Due to the presence of arrays (which are functions from integers to reals) the logic #( # id) is a High Order Mathematical Logic. due to the mentioned undecidability result holding for polynomial formulae on integer variables) However, if one considers only linear ....

.... relation if it satisfies the properties of x x for all x 2 X, reflexivity x y if and only if y x, symmetry x y and y z then x z, transitivity It can be shown that every partition (X) induces an equivalence relation and, conversely, every equivalence relation induces a partition [10]. Two elements are related if they belong to the same partition. Every element i of the partition is then called an equivalence class. An equivalence class is often named after one of its representatives (any element of i can be taken as a representative) An alternative definition of an ....
