Weak Approximation for Linear Systems of Quadrics
We give local conditions at ∞ ensuring that the intersection of n quadrics in P , N ≫ n, satisfies weak approximation. Let K be a number field, V a finite-dimensional vector space over K, and W ⊂ Sym V ∗ a K-vector space of quadratic forms on V . We can regard W as a linear system of quadrics in PV , and we denote the intersection of all quadrics in the system XW . If S is a finite set of place...
متن کاملOn the Approximation of Pseudo Linear Systems by Linear Time Varying Systems (RESEARCH NOTE)
This paper presents a modified method for approximating nonlinear systems by a sequence of linear time varying systems. The convergence proof is outlined and the potential of this methodology is discussed. Simulation results are used to show the effectiveness of the proposed method.
متن کاملA weak approximation for the Extrema's distributions of Levy processes
Suppose that $X_{t}$ is a one-dimensional and real-valued L'evy process started from $X_0=0$, which ({bf 1}) its nonnegative jumps measure $nu$ satisfying $int_{Bbb R}min{1,x^2}nu(dx)
متن کاملDiophantine approximation on rational quadrics
We compute the Hausdorff dimension of sets of very well approximable vectors on rational quadrics. We use ubiquitous systems and the geometry of locally symmetric spaces. As a byproduct we obtain the Hausdorff dimension of the set of rays with a fixed maximal singular direction, which move away into one end of a locally symmetric space at linear depth, infinitely many times.
متن کاملModified Linear Approximation for Assessment of Rigid Block Dynamics
This study proposes a new linear approximation for solving the dynamic response equations of a rocking rigid block. Linearization assumptions which have already been used by Hounser and other researchers cannot be valid for all rocking blocks with various slenderness ratios and dimensions; hence, developing new methods which can result in better approximation of governing equations while keepin...
