Parton coalescence and spacetime

The influence of spacetime dynamics in hadronization via parton coalescence at RHIC is investigated using covariant parton transport theory. Key observables, the quark number scaling of elliptic flow and the enhancement of the p/pi ratio, show strong dynamical effects and differ from earlier results based on the simple coalescence formulas.Comment: Talk presented at the BP2004 Workshop (KFKI/RMKI, Budapest, March 24-27). 8 pages, 8 eps figs, stylefile included.

On isomorphisms of standard operator algebras

The aim of this paper is to show that between standard operator algebras every bijective map with a certain multiplicativity property related to Jordan triple isomorphisms of associative rings is automatically additive.Comment: 8 pages. To appear in Studia Mat

Sequential isomorphisms between the sets of von Neumann algebra effects

In this paper we describe the structure of all sequential isomorphisms between the sets of von Neumann algebra effects. It turns out that if the underlying algebras have no commutative direct summands, then every sequential isomorphism between the sets of their effects extends to the direct sum of a *-isomorphism and a *-antiisomorphism between the underlying von Neumann algebras.Comment: To appear in Acta Sci.
