ON MAXIMALLY INFLECTED HYPERBOLIC CURVES

by Aubin Arroyo, Lucia, López De Medrano
"... Abstract. In this note we study the distribution of real inflection points among the ovals of a real non-singular hyperbolic curve of even degree. Using Hilbert’s method we show that for any integers d and r such that 4 ≤ r ≤ 2d2 − 2d, there is a non-singular hyperbolic curve of degree 2d in R2 with ..."

Nuclear Physics B Proceedings Supplement – preprint (2014) 1–42 Nuclear Physics B Proceedings Supplement Universal Aspects of QCD-like TheoriesI

by Lorenz Von Smekal
"... In these lectures I review some basic examples of how the concepts of universality and scaling can be used to study aspects of the chiral and the deconfinement transition, if not in QCD directly but in QCD-like theories. As an example for flavor dynamics I discuss a quark-hadron model to describe th ..."
Abstract - Add to MetaCart
the phase diagram of two-color QCD with the functional renormalization group. Universal aspects of deconfinement are illustrated mainly in the 2 + 1 dimensional SU(N) gauge theories with second order transition where many exact results from spin models can be exploited.

"... We examine the late time behavior of the Bunch-Davies wavefunction for interacting light fields in a de Sitter background. We use perturbative techniques developed in the framework of AdS/CFT, and analytically continue to compute tree and loop level contributions to the Bunch-Davies wavefunction. We ..."

Akademisk avhandling för teknisk doktorsexamen vid

by Kungl Tekniska Högskolan, Kth Tryck , 1994
"... mcmxciv This thesis deals with combinatorics in connection with Coxeter groups, finitely generated but not necessarily finite. The representation theory of groups as nonsingular matrices over a field is of immense theoretical importance, but also basic for computational group theory, where the group ..."
Abstract - Add to MetaCart
the group elements are data structures in a computer. Matrices are unnecessarily large structures, and part of this thesis is concerned with small and efficient representations of a large class of Coxeter groups (including most Coxeter groups that anyone ever payed any attention to.)

1Achievable Rate Regions for Two-Way Relay Channel using Nested Lattice Coding

by Sinda Smirani, Mohamed Kamoun, Mireille Sarkiss, Abdellatif Zaidi, Pierre Duhamel
"... Abstract—This paper studies Gaussian Two-Way Relay Chan-nel where two communication nodes exchange messages with each other via a relay. It is assumed that all nodes operate in half duplex mode without any direct link between the communication nodes. A compress-and-forward relaying strategy using ne ..."
Abstract - Add to MetaCart
nested lattice codes is first proposed. Then, the proposed scheme is improved by performing a layered coding: a common layer is decoded by both receivers and a refinement layer is recovered only by the receiver which has the best channel conditions. The achievable rates of the new scheme

1Robust M-Estimation for Heavy Tailed Nonlinear AR-GARCH (with Supplemental Appendix C)

by Jonathan B. Hill , 2011
"... We develop new tail-trimmed M-estimation methods for heavy tailed Nonlinear AR-GARCH models. Tail-trimming allows both identi…cation of the true parameter and asymptotic normality for nonlinear models with asymmetric errors. In heavy tailed cases the rate of convergence is in…nitesimally close to th ..."
Abstract - Add to MetaCart

A simulation study shows the estimator trumps existing ones for AR and GARCH models based on sharpness
