Inherently improper surface parametric supports

چکیده
We identify a class of monomial supports that are inherently improper because any surface rational parametrization defined on them is improper. A surface support is inherently improper if and only if the gcd of the normalized areas of the triangular sub-supports is non-unity. The constructive proof of this claim can be used to detect all and correct almost all improper surface parametrizations due to improper supports.

Inherently Improper Parametric Supports for Unirational Varieties
A class of parametric supports in the lattice space Z is found to be inherently improper because any rational parametrization from C to C defined on such a support is improper. For a generic rational parametrization defined on an inherently improper support, we prove that its improper index is the gcd of the normalized volumes of all the simplex sub-supports and give an algorithm to obtain a pr...
متن کاملThe marginalization paradox does not imply inconsistency for improper priors
The marginalization paradox involves a disagreement between two Bayesians who use two different procedures for calculating a posterior in the presence of an improper prior. We show that the argument used to justify the procedure of one of the Bayesians is inapplicable. There is therefore no reason to expect agreement, no paradox, and no evidence that improper priors are inherently inconsistent....
متن کاملMarkov Chain Conditions for Admissibility in Estimation Problems with Quadratic Loss
Consider the problem of estimating a parametric function when the loss is quadratic. Given an improper prior distribution, there is a formal Bayes estimator for the parametric function. Associated with the estimation problem and the improper prior is a symmetric Markov chain. It is shown that if the Markov chain is recurrent, then the formal Bayes estimator is admissible. This result is used to...
متن کاملNumerical proper reparametrization of parametric plane curves
Proper reparametrization is a basic simplifying process for rational parameterized curves. There are complete results proposed for the curves with exact coefficients but few papers discuss the situations with numerical coefficients which have many practical applications. In this paper, we deal with mathematical objects that are assumed to be given approximately. The approximate improper index i...
متن کاملComputations with Differential Rational Parametric Equations
This paper studies several computational problems about differential rational parametric equations. We present a method of implicitization for general differential rational parametric equations. We also present a method to decide whether the parameters of a set of parametric equations are independent, and if not, re-parameterize the parametric equations so that the new parametric equations have...
