Positive automorphisms for self-induced interval exchange transformations
Positive automorphisms self-induced interval exchange transformations Dynamical Systems
2011/9/5
Abstract: We give an algorithm to determine if the dynamical system generated by a positive automorphism of the free group can also be generated by a self-induced interval exchange transformation. The...
Two-Photon Exchange Effect Studied with Neural Networks
Two-Photon Exchange Neural Networks
2011/7/21
The novel approach to the extraction of the two-photon exchange (TPE) correction from the elastic $ep$ scattering data is presented. The Bayesian framework for the neural networks is adapted. As the r...
Pentagonal Relations and the Exchange Module of the Type $A_n$ Cluster Algebra
Associahedron Cluster Algebra Discrete Homotopy Theory
2011/1/21
In this paper we study relations between the exchange relations in the cluster algebra of type-An, which has the 1-skeleton of the associahedron as its exchange graph, and the complex of triangulation...
Exchange between perverse and weight filtration for the Hilbert schemes of points of two surfaces
Exchange perverse weight filtration Hilbert schemes points of two surfaces
2011/1/21
We show that a natural isomorphism between the rational cohomology groups of the two zero-dimensional Hilbert schemes of n-points of two surfaces, the affine plane minus the axes and the cotangent bun...
Stratified economic exchange on networks
Physics and Society (physics.soc-ph) Social and Information Networks (cs.SI) Cellular Automata and Lattice Gases (nlin.CG)
2010/11/10
We investigate a model of stratified economic interactions between agents when the notion of spatial location is introduced. The agents are placed on a network with near-neighbor connections. Interact...
Sparse paving matroids, basis-exchange properties, and cyclic flats
Sparse paving matroids basis-exchange properties cyclic flats
2010/11/9
We provide evidence for five long-standing, basis-exchange conjectures for matroids by proving them for the enormous class of sparse paving matroids. We also explore the role that these matroids may p...
Sensitivity of the Performance of a Simple Exchange Model to its Topology
Simple Exchange Topology
2010/4/27
We study a simple exchange model in which price is fixed and the amount of a good transferred between actors depends only on the actors' respective budgets and the existence of a link between transact...
The martingale approach for credit-risky exchange option pricing
Exchange option Girsanov’s theorem
2010/9/10
An exchange option allows its holder to exchange one asset for another at maturity. In this short paper, the martingale approach, which is based on Continuous martingale representation theorem and Gir...
Improved Zonal Method Predictions in a Rectangular Furnace by Smoothing the Exchange Areas
Zone method exchange areas smoothing methods rectangular enclosure
2009/10/9
A numerical study was conducted by the means of the Hottel’s zone method based on the concept of the exchange areas associated with the weighted sum of grey gases model (WSGG model). 2D computational ...
A state space search algorithm and its application to learn the short-term foreign exchange rates
State space search discrete recurrent neural networks absolutelystable foreign exchange rates
2010/9/13
We propose the use of a state space search algorithm of the discretetime recurrent neural network to learn the short-term foreign exchange rates. By searching in the neighborhood of the target traject...
Testing for Long Memory in the Asian Foreign Exchange Rates
Exchange rates long memory plug-in method Whittle method
2007/12/11
In this paper, we use the plug-in and Whittle methods that are based on spectral regression analysis to test for the long memory property in 12 Asian/dollar daily exchange rates. The results according...
