A new definition of the intermediate group of gamma-ray bursts
I. Horvath, L. G. Balazs, Z. Bagoly +2
Gamma-ray bursts can be divided into three groups ("short", "intermediate", "long") with respect to their durations. This classification is somewhat imprecise, since the subgroup o…
Bottomonia correlators and spectral functions at zero and finite temperature
K. Petrov, A. Jakovac, P. Petreczky +1
We present preliminary studies of bottomonia spectral functions at zero and finite temperature using quenched anisotropic lattices. The heavy quark is treated within Fermilab appro…
Fixation of strategies for an evolutionary game in finite populations
Tibor Antal, Istvan Scheuring
A stochastic evolutionary dynamics of two strategies given by 2 x 2 matrix games is studied in finite populations. We focus on stochastic properties of fixation: how a strategy rep…
A geometric classification of immersions of 3-manifolds into 5-space
Andras Juhasz
In this paper we define two regular homotopy invariants c and i for immersions of oriented 3-manifolds into R^5 in a geometric manner. The pair (c(f),i(f)) completely describes the…
Regular homotopy classes of singular maps
Andras Juhasz
Two locally generic maps f,g : M^n --> R^{2n-1} are regularly homotopic if they lie in the same path-component of the space of locally generic maps. Our main result is that if n is…
Regular homotopy classes of locally generic mappings
Andras Juhasz
In this paper we generalize the notion of regular homotopy of immersions of a closed connected n-manifold into R^{2n-1} to locally generic mappings. The main result is that if n=2…
