Novel Explicit Multi Spin String Solitons in AdS(5)
A. L. Larsen, A. Khan
We find new explicit solutions describing closed strings spinning with equal angular momentum in two independent planes in AdS(5). These are 2N-folded strings in the radial directi…
Purely infinite C*-algebras: ideal-preserving zero homotopies
Eberhard Kirchberg, Mikael Rordam
We show that if A is a separable, nuclear, O_infty-absorbing (or strongly purely infinite) C*-algebra, which is homotopic to zero in an ideal-system preserving way, then A is the i…
Neutrino cosmology - an update
Steen Hannestad
Present cosmological observations yield an upper bound on the neutrino mass which is significantly stronger than laboratory bounds. However, the exact value of the cosmological bou…
Cosmological mass limits on neutrinos, axions, and other light particles
Steen Hannestad, Georg Raffelt
The small-scale power spectrum of the cosmological matter distribution together with other cosmological data provides a sensitive measure of the hot dark matter fraction, leading t…
Reconstructing the primordial power spectrum - a new algorithm
Steen Hannestad
We propose an efficient and model independent method for reconstructing the primordial power spectrum from Cosmic Microwave Background (CMB) and large scale structure observations.…
On the universal property of Pimsner-Toeplitz C*-algebras and their continuous analogues
Ilan Hirshberg
We consider C*-algebras generated by a single Hilbert bimodule (Pimsner-Toeplitz algebras) and by a product systems of Hilbert bimodules. We give a new proof of a theorem of Pimsne…
