Infinite Idealizations
1. Approximations of arbitrarily large but finite systems are often mistaken for infinite idealizations in statistical and thermal physics. The problem is illustrated by thermodynamically reversible processes. They are approximations of processes requiring arbitrarily long, but finite times to complete, not processes requiring an actual infinity of time. 2. The present debate over whether phase...
متن کاملThe Nagata automorphism is wild.
It is proved that the well known Nagata automorphism of the polynomial ring in three variables over a field of characteristic zero is wild, that is, it can not be decomposed into a product of elementary automorphisms.
متن کاملNetwork Virtualization Idealizations for Applications
Due to limitations of today’s widely-deployed commercial networks, some end-user applications are only possible through, or greatly improved by execution on virtualized networks that have been enhanced or idealized in a way which specifically supports the application. This paper describes US Ignite and the advantages provided to US Ignite end-user applications running on virtual networks which ...
متن کاملSmooth Extensions for a Finite Cw Complex
The C* -algebra extensions of a topological space can be made into an abelian group which is naturally equivalent to the Khomology group of odd dimension [1] which has a close relation with index theory and is one of the starting points of KK theory [8]. The Cp -smoothness of an extension of a manifold was introduced in [3, 4], where Cp denotes the Schatten-von Neumann p-class [5]. We generaliz...
متن کاملOn the Nagata Problem
In the course of his construction [N] of a counterexample to Hilbert's 14th problem, Nagata was led to formulate a conjectural lower bound on the degree of a plane curve having assigned multiplicities at a generic collection of points. To state the conjecture precisely, recall first that the multiplicity mult P (C) of an arbitrary plane curve C (=pos
