Last time we discussed two main categories of linear models, and their combination. Here w t denotes a white noise: a stationary process with E w t = 0, E w 2 t = σ 2 , and E w t w s = 0 for s = t. MA(q) x t = µ + w t + q j=1 θ j w t−j = µ + w t + θ 1 w t−1 + · · · + θ q w t−q. x t is stationary with well-defined variance and covariances for any values of the coefficients θ 0 ,. .. , θ q , if q...
where p(t, z), ~(2, t) are the mean density and velocity of the flow, p(z, t) is the pressure. Assume the gas under consideration is polytropic. Then the temperature, density, and pressure are related with RT = p/p where R is a positive constant proportional to the molecular weight of gas and assumed to be unit for simplicity. So p = Tp. Roughly speaking, the pressure p vanishes as T goes to ze...
بنابر اصل ماکزیمم قدر مطق اگر p(z) تابع تحلیلی غیر ثابت ودر میدان کراندار d پیوسته باشد وبر بستار آن نیز پیوسته باشد |p(z) | ماکزیممی در d ندارد مگر اینکه تابع ثا بت با شد. فرض کنیم p(z) چند جمله ای از درجه n باشد و ?p?_p=?(1/2? ?_0^2??|p(e^i? ) |^p )?^(1/p) نامساوی های l^p راباتوجه به محل قرار گرفتن ریشه های p(z) درصفحه وتعمیم آنها رابررسی می کنیم.
Let X, Y and Z be Banach spaces, and let ∏ p(Y, Z) (1 ≤ p < ∞) denote the space of p-summing operators from Y to Z. We show that, if X is a £∞-space, then a bounded linear operator T : X⊗̂ǫY −→ Z is 1-summing if and only if a naturally associated operator T : X −→ ∏ 1(Y, Z) is 1-summing. This result need not be true if X is not a £∞-space. For p > 1, several examples are given with X = C[0, 1] t...
In 1921 Blichfeldt gave an upper bound on the number of integral points contained in a convex body in terms of the volume of the body. More precisely, he showed that #(K∩Z) ≤ n! vol(K)+n, whenever K ⊂ R is a convex body containing n+1 affinely independent integral points. Here we prove an analogous inequality with respect to the surface area F(K), namely #(K ∩ Z) < vol(K) + ((√n + 1)/2) (n − 1)...
Proefschrift ingediend tot het behalen van de graad van Doctor in de Wetenschappen december 2004 ii Introduction Let f be a polynomial in Z[x], x = (x 1 ,. .. , x m), defining a hypersurface X 0 in A m Z. Igusa's Monodromy Conjecture predicts an intriguing relationship between the arithmetic properties of f , and the topology of the (not necessarily reduced) complex hypersurface X 0 = X 0 × Spe...
