Mathematical gauge concept experiences connections on vital bundles, or, extra accurately, the answer areas of yes partial differential equations for such connections. traditionally, those equations have come from mathematical physics, and play a massive position within the description of the electro-weak and powerful nuclear forces. using gauge concept as a device for learning topological homes of four-manifolds was once pioneered by way of the elemental paintings of Simon Donaldson within the early Nineteen Eighties, and used to be revolutionized by way of the advent of the Seiberg-Witten equations within the mid-1990s. because the start of the topic, it has retained its shut reference to symplectic topology. The analogy among those fields of analysis was once extra underscored through Andreas Floer's development of an infinite-dimensional variation of Morse idea that applies in a priori diversified contexts: both to outline symplectic invariants for pairs of Lagrangian submanifolds of a symplectic manifold, or to outline topological invariants for three-manifolds, which have compatibility right into a framework for calculating invariants for tender four-manifolds. "Heegaard Floer homology", the recently-discovered invariant for 3- and four-manifolds, comes from an software of Lagrangian Floer homology to areas linked to Heegaard diagrams. even supposing this conception is conjecturally isomorphic to Seiberg-Witten idea, it's extra topological and combinatorial in style and hence more uncomplicated to paintings with in convinced contexts. The interplay among gauge conception, low-dimensional topology, and symplectic geometry has ended in a couple of awesome new advancements in those fields. the purpose of this quantity is to introduce graduate scholars and researchers in different fields to a few of those fascinating advancements, with a distinct emphasis at the very fruitful interaction among disciplines. This quantity relies on lecture classes and complex seminars given on the 2004 Clay arithmetic Institute summer season tuition on the Alfr?d R?nyi Institute of arithmetic in Budapest, Hungary. a number of of the authors have further a large amount of extra fabric to that awarded on the university, and the ensuing quantity presents a cutting-edge advent to present study, overlaying fabric from Heegaard Floer homology, touch geometry, tender four-manifold topology, and symplectic four-manifolds. Titles during this sequence are copublished with the Clay arithmetic Institute (Cambridge, MA).

Attribute sessions are important to the trendy learn of the topology and geometry of manifolds. They have been first brought in topology, the place, for example, they can be used to outline obstructions to the lifestyles of yes fiber bundles. attribute periods have been later outlined (via the Chern-Weil thought) utilizing connections on vector bundles, hence revealing their geometric part. within the past due Nineteen Sixties new theories arose that defined nonetheless finer buildings. Examples of the so-called secondary attribute sessions got here from Chern-Simons invariants, Gelfand-Fuks cohomology, and the attribute periods of flat bundles. the hot recommendations are fairly beneficial for the research of fiber bundles whose constitution teams are usually not finite dimensional. the speculation of attribute periods of floor bundles may be the main constructed. right here the certain geometry of surfaces permits one to attach this idea to the speculation of moduli area of Riemann surfaces, i.e., Teichmuller thought. during this booklet Morita provides an advent to the trendy theories of attribute sessions.
