We study the numerical approximation of fractional powers of accretive operators in this paper. Namely, if A is the accretive operator associated with an accretive sesquilinear form A(·, ·) defined on a Hilbert space V contained in L(Ω), we approximate A for β ∈ (0, 1). The fractional powers are defined in terms of the so-called Balakrishnan integral formula. Given a finite element approximatio...
La nueva física puede manifestarse a través de correcciones virtuales que generan las partículas exóticas. En el escenario del modelo Bestest Little Higgs, contribuciones surgen los vértices Z q_i anti-q_i y t S_i, con q_i=b, t, B, T, T_5, T_6, T^2/3 S_i=h_0, H_0, A^0, phi^0, eta^0, sigma, H^±, phi^±, eta^±. Con estos nuevos se calculan nivel un lazo al momento dipolar magnético débil anómalo q...
Let $\mathbb{B}(\mathcal{H})$ denote the $C^{\ast}$-algebra of all bounded linear operators on a Hilbert space $\big(\mathcal{H}, \langle\cdot, \cdot\rangle\big)$. Given positive operator $A\in\B(\h)$, and number $\lambda\in [0,1]$, seminorm ${\|\cdot\|}_{(A,\lambda)}$ is defined set $\B_{A^{1/2}}(\h)$ in $\B(\h)$ having an $A^{1/2}$-adjoint. The combination sesquilinear form ${\langle \cdot, \...
In this paper we aim to construct an abstract model of a differential operator with fractional integro-differential composition in final terms, where modeling is understood as interpretation concrete operators terms the infinitesimal generator corresponding semigroup. We study such Kipriyanov operator, Riesz potential, difference operator. Along this, consider transforms m-accretive generalizat...
We generalize the symmetron screening mechanism by allowing for an explicit symmetry breaking of ${\ensuremath{\phi}}^{4}$ potential. A coupling to matter form $A(\ensuremath{\phi})=1+\frac{{\ensuremath{\phi}}^{2}}{{M}^{2}}$ leads explicitly broken with effective potential ${V}_{\mathrm{eff}}(\ensuremath{\phi})=\ensuremath{-}{\ensuremath{\mu}}^{2}(1\ensuremath{-}\frac{\ensuremath{\rho}}{{\ensur...
A study was conducted to examine the time required to process lateral motion and motion-in-depth for luminance- and disparity-defined stimuli. In a 2 × 2 design, visual stimuli oscillated sinusoidally in either 2D (moving left to right at a constant disparity of 9 arcmin) or 3D (looming and receding in depth between 6 and 12 arcmin) and were defined either purely by disparity (change of dispari...
Let $$\Omega \subset {{\mathbb {R}}}^3$$ be an open set. We study the spectral properties of free Dirac operator $$ \mathcal {H} :=- i \alpha \cdot \nabla + m\beta coupled with singular potential $$V_\kappa =(\epsilon I_4 +\mu \beta \eta (\alpha N))\delta _{\partial \Omega }$$ , where $$\kappa ,\mu ,\eta )\in . The set can either a $$\mathcal {C}^2$$ -bounded domain or locally deformed half-spa...
On a spin manifold with conformal cusps, we prove under an invertibility condition at infinity that the eta function of the twisted Dirac operator has at most simple poles and is regular at the origin. For hyperbolic manifolds of finite volume, the eta function of the Dirac operator twisted by any homogeneous vector bundle is shown to be entire.
We search for B meson decays into two-body combinations of eta, eta', omega, and phi mesons from 89 x 10(6) BB pairs collected with the BABAR detector at the PEP-II asymmetric-energy e+e- collider at SLAC. We find the branching fraction B(B0-->etaomega)=(4.0(+1.3)(-1.2)+/-0.4)x10(-6) with a significance of 4.3 sigma. For the other decay modes we set the following 90% confidence level upper limi...
In this paper, we study the following operator equation: p ∈ Ax + Cx in a Banach space X , where A : D(A) ⊆ X → 2X is an accretive mapping, C : D(C) ⊆ X → X is a nonlinear mapping and p ∈ X . Various existence results of solutions of nonlinear operator equations in Banach spaces are obtained under a countably condensing type condition. © 2004 Elsevier Ltd. All rights reserved.
