Further Results on Lusin’s Theorem for Uncertain Variables

open access: yesSymmetry
In order to treat the degree of belief rationally, Baoding Liu created uncertainty theory. An uncertain variable, as a measurable function from an uncertainty space to the set of real numbers, is a basic concept in uncertainty theory.

Lusin theorem, GLT sequences and matrix computations: An application to the spectral analysis of PDE discretization matrices

open access: yesJournal of Mathematical Analysis and Applications, 2017
In this paper we consider a general d-dimensional second-order elliptic Partial Differential Equation (PDE) with variable coefficients, and we extend previous results on the spectral distribution of discretization matrices arising from B-spline ...

On a Theorem of Banach and Kuratowski and $K$-Lusin Sets

open access: yesRocky Mountain Journal of Mathematics, 2003
In a paper of 1929, Banach and Kuratowski proved, assuming the continuum hypothesis, a combinatorial theorem which implies that there is no non-vanishing sigma-additive finite measure on the real line which is defined for every set of reals. It will be shown that the combinatorial theorem is equivalent to the existence of a K-Lusin set of size the ...

ON LUSIN'S THEOREM IN THE ASPECT OF SMALL SYSTEMS

open access: yesDemonstratio Mathematica, 1995
Let \(S\) be a \(\sigma\)-algebra of subsets of a set \(X\). By a small system a sequence of families \((N_n)_n\subset S\) satisfying some axioms is understood. If \(m\) is a positive measure, then the family \(N_n\) of all sets of a measure less than \(1/n\) can serve as an example.

Normal bundle and Almgren’s geometric inequality for singular varieties of bounded mean curvature [PDF]

open access: yesBulletin of Mathematical Sciences, 2020
In this paper we deal with a class of varieties of bounded mean curvature in the viscosity sense that has the remarkable property to contain the blow up sets of all sequences of varifolds whose mean curvatures are uniformly bounded and whose boundaries ...

Lusin-type theorem for functions with prescribed gradient [PDF]

open access: yes
openIn the first part of this thesis we discuss and prove a theorem by Giovanni Alberti whose statement shares similarities to that of Lusin's Theorem, hence the "Lusin-type theorem" definition.

A Constructive Version of the Lusin Separation Theorem

open access: yes, 2009
I state and prove a constructive version of the Lusin Separation Theorem. The classical statement of the theorem is that disjoint analytic sets are Borel separable. The definitions and results are carried out in the axiom system CZF for constructive set theory.

Variations on Lusin's Theorem [PDF]

open access: yesTransactions of the American Mathematical Society, 1987
We prove a theorem about continuous restrictions of Marczewski measurable functions to large sets. This theorem is closely related to the theorem of Lusin about continuous restrictions of Lebesgue measurable functions to sets of positive measure and the theorem of Nikodým and Kuratowski about continuous restrictions of functions with the Baire property
