The geometry part of the text includes an introductory course on projective geometry and some chapters on symmetry. Surprising relationships, called dualities, between seemingly different forms of string theory, based on relationships between different toploogies for the "compact" dimensions of spacetime. Within those themes, a partial list of topics would include: BV algebras; operads; the Fukaya category; various compactifications of moduli spaces of stable curves and stable maps, as in string topology and contact homology and twisted K-theory.

A month after the class was over a professor asked me what a manifold was, and I couldn't answer him. Hopefully you can tighten everything up into a rigorous argument, or at least get started :] The main point will be to show that the map from good path to words in a and b is a isomorphism. The book suffers in comparison to the one by Fomenko, Fuchs and Gutenmacher (Homotopic Topology), but that, alas, can't be had for love or money.

After a brief description of some aspects of topological string theory and its relation to Chern-Simons theory, we discuss possible geometric explanations of the recently observed relation between knot contact homology and open topological strings. We prove that such a set has size at least a constant multiple of q^{cn/k}. Algebro-geometric approaches to tensor spaces, tensor decomposition, and identifiability.

Geom.} Senior members currently supervise Master and Ph. Michael Guy (Valery Alexeev), Moduli of Weighted Stable Maps and Their Gravitational Descendants. The most general way to classify manifolds is in terms of "homeomorphisms". But because polynomials are so ubiquitous in mathematics, algebraic geometry has always stood at the crossroads of many different fields. The motivic Hodge characteristic. 3) Mixed Hodge theory of degenerations.

Also a wonderful section on scale size examples from the atomic & molecular to the cellular and macromolecular. [If you have a slow connection, turn off auto-images and select later.] ASK DR. Three approaches can be distinguished: Hippocrates’ dodge of substituting one problem for another; the application of a mechanical instrument, as in Hippias’s device for trisecting the angle; and the technique that proved the most fruitful, the closer and closer approximation to an unknown magnitude difficult to study (e.g., the area of a circle) by a series of known magnitudes easier to study (e.g., areas of polygons)—a technique known in modern times as the “ method of exhaustion ” and attributed by its greatest practitioner, Archimedes, to Plato’s student Eudoxus of Cnidus (c. 408–c. 355 bce).
