-polynomials of finite monoids of Lie type
Kürşat Aker, Mahir Bilen Can, Müge Taşkín
This paper concerns the combinatorics of the orbit Hecke algebra associated with the orbit of a two sided Weyl group action on the Renner monoid of a finite monoid of Lie type, …
Cosmological particle creation: Fluctuations and an ensemble picture
Ali Kaya
We point out that in the context of quantum fields in time dependent classical backgrounds, the number of created particles with a given momentum largely deviates about its mean va…
Symmetry analysis and exact solutions of modified Brans-Dicke cosmological equations
Metin Arik, Mikhail B. Sheftel
We perform a symmetry analysis of modified Brans-Dicke cosmological equations and present exact solutions. We discuss how the solutions may help to build models of cosmology where,…
First Observation of the Cabibbo-suppressed Decays Xi_c+ -> Sigma+ pi- pi+ and Xi_c+ -> Sigma- pi+ pi+ and Measurement of their Branching Ratios
SELEX Collaboration, E. Vazquez-Jauregui, J. Engelfried
We report the first observation of two Cabibbo-suppressed decay modes, Xi_c+ -> Sigma+ pi- pi+ and Xi_c+ -> Sigma- pi+ pi+. We observe 59+/-14 over a background of 87, and 22+/-8 o…
Self-dual gravity is completely integrable
Y. Nutku, M. B. Sheftel, J. Kalayci +1
We discover multi-Hamiltonian structure of complex Monge-Ampere equation (CMA) set in a real first-order two-component form. Therefore, by Magri's theorem this is a completely inte…
Quantum Mechanical Breakdown of Perfect Homogeneity in Reheating After Inflation
Ali Kaya
In the context of quantum fields in time dependent classical backgrounds, we notice that the number of created particles with a given momentum largely deviates about its mean value…
