Implicit polynomials implicit polynomial 2d curves and 3d surfaces are potentially among the most useful object and data representations for use in computer vision and image analysis because of their interpolation property, euclidean and affine invariants, as well as their ability to represent complicated objects.
The arnoldi process is a well known technique for approximating a few eigenvalues and corresponding eigenvectors of a general square matrix.
Each of these shift cycles results in the implicit application of a polynomial in of degree p to the starting vector. The roots of this polynomial are the shifts used in the qr process and these may be selected to filter unwanted information from the starting vector and hence from the arnoldi factorization.
Ing vector through implicit application of a polynomial filter to this vectoron each iteration. The implicit application of this polynomial filteris accomplished through.
The semi-implicit stabilization scheme, characteristic-based polynomial pressure projection (cbp3) consists of the characteristic-galerkin method and polynomial pressure projection. Theoretically, the proposed scheme works for any type of element using equal-order approximation for velocity and pressure. In this work, linear 3-node triangular and 4-node tetrahedral elements are the focus, which are the simplest but most difficult elements for pressure stabilizations.
We study the existence problem for a local implicit function determined by a system of nonlinear algebraic equations in the particular case when the determinant of its jacobian matrix vanishes at the point under consideration. We present a system of sufficient conditions that implies existence of a local implicit function as well as another system of sufficient conditions that guarantees.
