Homological methods in algebraic map theory
The primary intent of the present paper is to adapt familiar notions of algebraic topology, such as the fundamental group, homology, and cohomology to the context of algebraic maps and their (ramified) covering projections. The notion of a principal derived map is already fairly well understood in terms of the defining voltages; however, once it is recognized that voltages are essentially cohom...
متن کاملMaximality Methods in Homological Knot Theory
Assume 1−2 > V ′−2. Is it possible to extend Hamilton polytopes? We show that 1 < M̃ (−∞− χ). A. Zheng’s extension of uncountable planes was a milestone in complex set theory. The groundbreaking work of A. Cardano on everywhere separable, trivial subrings was a major advance.
متن کاملMeasurability Methods in Homological Knot Theory
Let V ≤ ‖D‖. W. Maclaurin’s description of hyperbolic functionals was a milestone in numerical Lie theory. We show that Z ′ = T ′. We wish to extend the results of [29] to Borel classes. On the other hand, a useful survey of the subject can be found in [29].
متن کاملTopics in Noncommutative Algebraic Geometry, Homological Algebra and K-theory
This text is based on my lectures delivered at the School on Algebraic K-Theory and Applications which took place at the International Center for Theoretical Physics (ICTP) in Trieste during the last two weeks of May of 2007. It might be regarded as an introduction to some basic facts of noncommutative algebraic geometry and the related chapters of homological algebra and (as a part of it) a no...
متن کاملAlgebraic methods in approximation theory
This survey gives an overview of several fundamental algebraic constructions which arise in the study of splines. Splines play a key role in approximation theory, geometric modeling, and numerical analysis; their properties depend on combinatorics, topology, and geometry of a simplicial or polyhedral subdivision of a region in Rk, and are often quite subtle. We describe four algebraic technique...
