This appendix contains: identification and estimation results on higher-order moments (Section A), some results on efficiency bounds calculations (Sections B and C) and the computation of asymptotic standard errors (Section D); additional computations for the examples treated in the text (Section E); an outline of a test of the covariance structure of errors (Section F); the calculation of the ...
We give a brief survey of the main results of [C04] and [C11], devoted to the bimeromorphic structure of compact Kähler manifolds X. Such manifolds are decomposed by means of iterated fibrations into elementary components, which are orbifold pairs with a canonical bundle either positive, negative, or torsion. Towers of ‘torsion and negative’ components build however the new (unconditional) clas...
Let σ be a constant in the interval (0, 1), and let A be an infinite set of positive integers which contains at least c1x σ and at most c2x σ elements in the interval [1, x] for some constants c2 > c1 > 0 independent of x and each x ≥ x0. We prove that then the sumset A + A has more elements than A (counted up to x) by a factor c(σ) √ log x/ log log x for x large enough. An example showing that...
2014 The elastic constants of cyanoadamantane have been measured in the plastic and « glassy » crystal phases. A special attention has been given to the temperature evolution of C11 as well as to the damping of the corresponding mode. Comparison with neutron results shows a strong dispersion at room temperature. The temperature dependence of C11 in the plastic phase has been explained by the se...
An interventionist account of causation characterizes causal relations in terms of changes resulting from particular interventions. I provide a new example of a causal relation for which there does not exist an intervention satisfying the common interventionist standard. I consider adaptations that would save this standard and describe their implications for an interventionist account of causat...
This report explores the way LLVM generates the memory barriers needed to support the C11/C++11 atomics for ARM. I measure the influence of memory barriers on performance, and I show that in some cases LLVM generates too many barriers. By leaving these barriers out, performance increases significantly. I introduce two LLVM passes, which will remove these extra barriers, improving performance in...
Let X be a definably compact definable C manifold and 2 ≤ r < ∞. We prove that the set of definable Morse functions is open and dense in the set of definable C functions on X with respect to the definable C topology.
Using a numerical method based on sub-super solution, we will obtain positive solution to the coupled-system of boundary value problems of the form −∆u(x) = λf(x, u, v) x ∈ Ω −∆v(x) = λg(x, u, v) x ∈ Ω u(x) = 0 = v(x) x ∈ ∂Ω where f , g are C functions with at least one of f(x0, 0, 0) or g(x0, 0, 0) being negative for some x0 ∈ Ω (semipositone).
Resonant motions of integrable systems subject to perturbations may continue to exist and to cover surfaces with parametric equations admitting a formal power expansion in the strength of the perturbation. Such series may be, sometimes, summed via suitable sum rules defining C functions of the perturbation strength: here we find sufficient conditions for the Borel summability of their sums in t...
