Full-overlap U+U collisions provide significantly larger initial energy densities at comparable spatial deformation, and significantly larger deformation and volume at comparable energy density, than semi-central Au+Au collisions. We show quantitatively that this provides a long lever arm for studying the hydrodynamic behavior of elliptic flow in much larger and denser collision systems and the...

A quark interaction with topologically nontrivial gluonic fields, instantons and sphalerons, violates P and CP symmetry. In the strong magnetic field of a noncentral nuclear collision such interactions lead to the charge separation along the magnetic field, the so-called chiral magnetic effect (CME). Recent results from the STAR collaboration on charge dependent correlations are consistent with...

We consider the 3D equation $u_{yy} = u_{tx} + u_yu_{xx} - u_xu_{xy}$ and its 2D reductions: (1) (u_y+y)u_{xx}-u_xu_{xy}-2$ (which is equivalent to Gibbons-Tsarev equation) (2) (u_y+2x)u_{xx} (y-u_x)u_{xy} -u_x$. Using reduction of known Lax pair for equation, we describe nonlocal symmetries of~(1) and~(2) show that Lie algebras these are isomorphic Witt algebra.

We prove the Gan–Gross–Prasad conjecture for U(n)×U(n) under some local conditions using a relative trace formula. We deduce some new cases of the Gan–Gross–Prasad conjecture for U(n+1)×U(n) from the case of U(n)×U(n).

The concept of a uniform density of subsets A of the set N of positive integers was introduced in [1] and [2]. Corresponding Iu convergence to the notion of uniform density u can be found in [8]. This paper studies Iu convergence in detail.

• BioGeoChemie des Watts Auf Beschluss der Deutschen Forschungsgemeinschaft wird an der Universität Oldenburg für die Dauer von sechs Jahren eine Forschergruppe "BioGeoChemie des Watts" eingerichtet. In den ersten drei Jahren erhält die Gruppe fast sechs Millionen DM Förderung. Der Antrag wurde federführend vom Institut für Chemie und Biologie des Meeres (ICBM) vorbereitet. Beteiligt sind außer...
