On Real-oriented Johnson-Wilson cohomology

Answering a question of W. S. Wilson, I introduce a Z/2equivariant Atiyah-Real analogue of Johnson-Wilson cohomology theory BP 〈n〉, whose coefficient ring is the ≤ n-chromatic part of Landweber’s Real cobordism ring. AMS Classification 55P42, 55P91; 55T25

Real - time simulations and the electroweak phase transition

Nonequilibrium quantum eld theory is important in various physical situations, such as domain formation during cosmological phase transitions and the properties of the electroweak transition in the early universe, or the QCD transition in heavy ion collisions. We concentrate in this talk on the SU(2)-Higgs model and the electroweak transition, which is relevant to theories of baryogenesis [1]. ...

Some Useful Background for Talk on the Fast Johnson-Lindenstrauss Transform

This writeup includes very basic background material for the talk on the Fast Johnson Lindenstrauss Transform on May 28th, 2007 by the author at the Summer School on Algorithmic Data Analysis in Helsinki, Finland. The talk is about the results in [2], but will be based on a new more recent proof (together with Edo Liberty), using more modern tools, such as probability in Banach spaces and error...

Surprising Areas in the Quest for Small Universal Devices

In this paper, we study a few points indicated in the talk which we presented at MFCSIT meeting in Cork. Our study concerns three main areas: Turing machines, cellular automata and hyperbolic cellular automata. The common thread is the quest for small universal devices. It leads from properties belonging to the classical domain up to results on super-Turing computations.
