In order to state our theorems we need to view the Seiberg-Witten invariant of a smooth 4manifold as a multivariable (Laurent) polynomial. To do this, recall that the Seiberg-Witten invariant of a smooth closed oriented 4-manifold X with b2 (X) > 1 is an integer valued function which is defined on the set of spin c structures over X, (cf. [W], [KM],[Ko1],[T1]). In caseH1(X,Z) has no 2-torsion (...

Coloring Maps and the Kowalski Doctrine

It is attractive to regard an algorithm as composed of the logic determining what the results are and the control determining how the result is obtained. Logic programmers like to regard programming as controlled deduction, and there have been several proposals for controlling the deduction expressed by a Prolog program and not always using Prolog’s normal backtracking algorithm. The present no...
