Analytic upper and lower bounds for the period of nonlinear oscillators

More specifically, we investigate whether a simple causal approach outperforms the forecasting accuracy of linear and nonlinear univariate models such as ARMA and

A similar problem – which is closely related to the original sum-product conjecture – is to bound the number of sums and ratios along the edges of a graph2. We give upper and

The main purpose of Part I is to prove precise quantitative local upper and lower bounds which combine into dierent forms of Harnack inequalities; as a consequence we also

We consider the general chiral effective action which parametrizes the nonlinear realization of the spontaneous breaking of the electroweak symmetry with a light Higgs boson and

In the previous sections we have shown how astronomical alignments and solar hierophanies – with a common interest in the solstices − were substantiated in the

We see that the problem of finding the distance of a linear code is quite complicated and, although it has been tackled by many different perspectives, it remains unsolved for

In the preparation of this report, the Venice Commission has relied on the comments of its rapporteurs; its recently adopted Report on Respect for Democracy, Human Rights and the Rule

In this paper we suggest two extensions of theChow and Lin (1971) method, the workhorse of the current literature on temporal interpolation: First, we will apply the procedure
