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 (...

Problematica are taxa that defy robust phylogenetic placement. Traditionally the term was restricted to fossil forms, but it is clear that extant taxa may be just as difficult to place, whether using morphological or molecular (nucleotide, gene or genomic) markers for phylogeny reconstruction. We discuss the kinds and causes of Problematica within the Metazoa, as well as criteria for their reco...

The subject of “wavelets” is expanding at such a tremendous rate that it is impossible to give, within these few pages, a complete introduction to all aspects of its theory. We hope, however, to allow the reader to become sufficiently acquainted with the subject to understand, in part, the enthusiasm of its proponents toward its potential application to various numerical problems. Furthermore, ...
