Crossed complexes and chain complexes with operators ∗ by RONALD BROWN
Chain complexes with a group of operators are a well known tool in algebraic topology, where they arise naturally as the chain complex C∗X̃ of cellular chains of the universal cover X̃ of a reduced CW -complex X. The group of operators here is the fundamental group of X. J.H.C. Whitehead in his classical but little read paper [31] showed that the chain complex C∗(X̃) is useful for the homotopy cla...

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 (...

The British race can claim with every truth that it has conferred many benefits upon this country; had it conferred no other than the gift of western medicine, the people of the sub-continent might still rise up and call it blessed. Of all the blessings which western medicine has been able to confer, none are surpassed by those which originate from the work of Sir Ronald Ross, k.c.b., k.c.m.g.,...
