Considering the Epistemic Uncertainties of the Variogram Model in Locating Additional Exploratory Drillholes [PDF]

open access: yesInternational Journal of Mining and Geo-Engineering, 2015
To enhance the certainty of the grade block model, it is necessary to increase the number of exploratory drillholes and collect more data from the deposit.

Orthogonal bases of Hermitean monogenic polynomials : an explicit construction in complex dimension 2 [PDF]

open access: yes, 2010
In this contribution we construct an orthogonal basis of Hermitean monogenic polynomials for the specific case of two complex variables. The approach combines group representation theory, see [5], with a Fischer decomposition for the kernels of each of ...

The Hasse norm principle for A-extensions [PDF]

open access: yesJournal of Number Theory, 2020
We prove that, for every $n \geq 5$, the Hasse norm principle holds for a degree $n$ extension $K/k$ of number fields with normal closure $F$ such that $\operatorname{Gal}(F/k) \cong A_n$. We also show the validity of weak approximation for the associated norm one tori.

Natural extension of the Generalised Uncertainty Principle

open access: yes, 2008
We discuss a gedanken experiment for the simultaneous measurement of the position and momentum of a particle in de Sitter spacetime. We propose an extension of the so-called generalized uncertainty principle (GUP) which implies the existence of a minimum

Local-global principles for norm one tori over semi-global fields

open access: yes, 2020
Let K be a complete discretely valued field with residue field k and F be a function field of a curve over K. Let L/F be a Galois extension of degree n. If n is coprime to char(k), then under some assumptions on k(e.g.

Testing the Gravitational Weak Equivalence Principle in the Standard-Model Extension with Binary Pulsars [PDF]

open access: yes, 2019
The Standard-Model Extension provides a framework to systematically investigate possible violation of the Lorentz symmetry. Concerning gravity, the linearized version was extensively examined.

An Extension of the Contraction Principle [PDF]

open access: yesJournal of Theoretical Probability, 2004
The ``contraction principle'' is about large deviations; the basic definitions figure in [\textit{A. Dembo} and \textit{O. Zeitouni}, ``Large deviation techniques and applications''. 2nd ed. (1998; Zbl 0896.60013)]. Its statement is (C). Let \((X_{n})\) satisfy the large deviation principle with good rate function \(I\) (defined on the metric space \({\

Friedrichs Extension and Min-Max Principle for Operators with a Gap

open access: yes, 2019
Semibounded symmetric operators have a distinguished self-adjoint extension, the Friedrichs extension. The eigenvalues of the Friedrichs extension are given by a variational principle that involves only the domain of the symmetric operator.
