When do neutrinos cease to oscillate ?
In order to investigate when neutrinos cease to oscillate in the framework of quantum field theory, we have reexamined the wave packet treatment of neutrino oscillations by taking different sizes of the wave packets of the particles involved in the production and detection processes. The treatment is shown to be considerably simplified by using the Grimus–Stockinger theorem which enables us to ...
متن کاملWhen is tit-for-tat unbeatable?
We characterize the class of symmetric two-player games in which tit-for-tat cannot be beaten even by very sophisticated opponents in a repeated game. It turns out to be the class of exact potential games. More generally, there is a class of simple imitation rules that includes tit-for-tat but also imitate-the-best and imitate-if-better. Every decision rule in this class is essentially unbeatab...
متن کاملNesterenko’s criterion when the small linear forms oscillate
In this paper we generalize Nesterenko’s criterion to the case where the small linear forms have an oscillating behaviour (for instance given by the saddle point method). This criterion provides both a lower bound for the dimension of the vector space spanned over the rationals by a family of real numbers, and a measure of simultaneous approximation to these numbers (namely, an upper bound for ...
متن کاملAll Solutions of the Diophantine Equation x 2 −
The main thrust of this article is to show how complete solutions of quadratic Diophantine equations can be given, for any positive discriminant, in terms of the continued fraction algorithm. This is in response to recent results by Zhang [4]-[6], wherein semi-simple continued fractions were introduced to generalize the well-known fact that solutions of quadratic Diophantine equations with valu...
متن کاملHow Does Calcium Oscillate?
Ca2+ is the most important second messenger in living cells serving as a critical link between a variety of extracellular stimuli and their intraand intercellular responses. The external signals are translated most often into repeated increases of the cytosolic Ca2+ concentration. Due to their importance and frequent appearance, Ca2+ oscillations have been extensively studied in experiments and...
