For a simply laced and hyperbolic Kac–Moody group G = G(R) over a commutative ring R with 1, we consider a map from a finite presentation of G(R) obtained by Allcock and Carbone to a representation–theoretic construction G(R) corresponding to an integrable representation V λ with dominant integral weight λ. When R = Z, we prove that this map extends to a group homomorphism ρλ,Z : G(Z)→ G(Z). We...
1 Algebras In this first section we will consider some common features of familiar algebraic structures such as groups, rings, lattices, and boolean algebras to arrive at a definition of a general algebraic structure. Recall that a group G consists of a nonempty set G, along with a binary operation · : G → G, a unary operation −1 : G → G, and a constant 1 G such that • x · (y · z) = (x · y) · z...
اندازه گیری نیروهای هیدرودینامیکی روی اجسام زیر آب یکی از نیازهای اساسی تونل آب می باشد. با توجه به محدودیت های تونل آب برای این کار یک بالانس دقیق نیرو لازم است. هدف از این مقاله طراحی، ساخت و کالیبراسیون یک بالانس شش مؤلفه ای جهت اندازه گیری نیروها و گشتاورهای وارده بر مدل در تست های مدلی استاتیکی و دینامیکی داخل تونل آب، می باشد. برای این منظور فرآیند تولید بالانس نیرو گشتاور شامل مراحل طراح...
and Applied Analysis 3 Theorem 4. Assume that (H 1 )–(H 6 ) and (7) hold. If there exists a function ξ(t) ∈ C rd(T , (0,∞)) such that for any positive numberM, lim t→∞ ∫ t t0 (ξ (s) p (s) − Q (s)) Δs = ∞, (12) where p (s) = q (s) [1 − p (δ (s))] β , Q (s) = αM(R (σ (s))) α−β r (δ (s)) ((ξ Δ (s)) + ) α+1 (α + 1) α+1 βξ (s) (δ (s)) α , (ξ Δ (s)) + := max {ξΔ (s) , 0} , (13) then (1) is oscillator...
Given a formal power series f(z) ∈ C[[z]] we define, for any positive integer r, its rth Witt transform, W (r) f , by W (r) f (z) = 1 r ∑ d|r μ(d)f(z d)r/d, where μ denotes the Möbius function. The Witt transform generalizes the necklace polynomials, M(α;n), that occur in the cyclotomic identity 1 1− αy = ∞
The global regularity problem for the periodic NavierStokes system ∂tu+ (u · ∇)u = ∆u−∇p ∇ · u = 0 u(0, x) = u0(x) for u : R×(R/Z) → R and p : R×(R/Z) → R asks whether to every smooth divergence-free initial datum u0 : (R/Z) 3 → R there exists a global smooth solution. In this note we observe (using a simple compactness argument) that this qualitative question is equivalent to the more quantita...
Suppose q(z) is a smooth function on [0,∞) whose odd order derivatives are zero at z=0. Take r = (x, y, z) and let U(r, t) be the solution of the the IBVP Utt − Uxx − Uyy − Uzz + q(z)U = 0 for r ∈ R, z ≥ 0, t ∈ R Uz(x, y, z=0, t) = δ(x, y, t), U(r, t) = 0, for t < 0 We show that q(z) may be recovered from a knowledge of U(a, b, 0, t) for t varying over an interval and fixed a, b, by reducing th...
We introduce a method to obtain the envelopes of eccentric orbits in axially symmetric potentials, $\Phi(R,z)$, endowed with $z$-symmetry reflection. By making transformation $z\rightarrow a+\sqrt{a^{2}+ z^{2}}$, $a>0$, we compute resulting mass density, referred here as \emph{effective density} $\rho_{\rm ef}(R,z;a)$, order calculate $Z(R)$ meridional plane $(R,z)$. find that they obey approxi...
