Of Minima and Maxima
Let h1, · · · , hn be positive integers. We study new sums m(h1, · · · , hn) = h1−1 ∑ r1=0 · · · hn−1 ∑ rn=0 min { r1 h1 , · · · , rn hn } and M(h1, · · · , hn) = h1−1 ∑ r1=0 · · · hn−1 ∑ rn=0 max { r1 h1 , · · · , rn hn } , the first of which times h1 · · ·hn is the number of lattice points in a pyramid of dimension n + 1. We show that m(h1, · · · , hn) (h1 − 1) · · · (hn − 1) = 1 + ∑ ∅6 =I⊆{1...
متن کاملGrand minima and maxima of solar activity: New observational constraints
Aims. Using a reconstruction of sunspot numbers stretching over multiple millennia, we analyze the statistics of the occurrence of grand minima and maxima and set new observational constraints on long-term solar and stellar dynamo models. Methods. We present an updated reconstruction of sunspot number over multiple millennia, from C data by means of a physics-based model, using an updated model...
متن کاملIndexing of time series by major minima and maxima
We describe a technique for fast compression of time series and indexing of compressed series. We have tested it on three data sets: stock prices, air and sea temperatures, and wind speeds.
متن کامل1 The Significance of Seismic Wavespeed Minima and Thermal Maxima
16 17 It is widely assumed that the boundary layer above the core is the source of intraplate volcanoes 18 such as Hawaii, Samoa and Yellowstone and that the sub-plate boundary layer at the top of the 19 mantle is thin and entirely subsolidus. In fact, this layer is thicker and has higher expansivity, 20 buoyancy and insulating power than the lower one, and may have higher potential temperature...
متن کاملAlternating minima and maxima, Nash equilibria and Bounded Arithmetic
We show that the least number principle for strict Σk formulas can be characterized by the existence of alternating minima and maxima of length k. We show simple prenex forms of these formulas whose herbrandizations (by polynomial time functions) are ∀Σ̂1 formulas that characterize ∀Σ̂1 theorems of the levels T k 2 of the Bounded Arithmetic Hierarchy, and we derive from this another characterizat...
