Directed Polymers with Constrained Winding Angle
Franco Ferrari, Vakhtang G. Rostiashvili, Thomas A. Vilgis
In this article we study from a non-perturbative point of view the entanglement of two directed polymers subjected to repulsive interactions given by a Dirac function potential…
Phantom Friedmann Cosmologies and Higher-Order Characteristics of Expansion
Mariusz P. Dabrowski, Tomasz Stachowiak
We discuss a more general class of phantom () cosmologies with various forms of both phantom (), and standard () matter. We show that many types of ev…
Observable Quantities in Cosmological Models with Strings
Mariusz P. Dabrowski, Jerzy Stelmach
The Friedman equation for the universe with arbitrary curvature , filled with mutually noninteracting pressureless dust, radiation, cosmological constant, and strin…
Inhomogenized sudden future singularities
Mariusz P. Dcabrowski
We find that sudden future singularities may also appear in spatially inhomogeneous Stephani models of the universe. They are temporal pressure singularities and may appear indepen…
Conformal relativity versus Brans-Dicke and superstring theories
David Blaschke, Mariusz P. Dabrowski
Conformal relativity theory which is also known as Hoyle-Narlikar theory has recently been given some new interest. It is an extended relativity theory which is invariant with resp…
Detecting linear dependence by reduction maps
Grzegorz Banaszak, Wojciech Gajda, Piotr Krason
We consider the local to global principle for detecting linear dependence of points in groups of the Mordell-Weil type. As applications of our general setting we obtain correspondi…
