On the local-indicability cohen–lyndon theorem

open access: yes, 2011
For a group H and a subset X of H, we let HX denote the set {hxh?1 | h ? H, x ? X}, and when X is a free-generating set of H, we say that the set HX is a Whitehead subset of H. For a group F and an element r of F, we say that r is Cohen–Lyndon aspherical

Voronovskaja type theorem for the Lupas, q-analogue of the Bernstein operators

open access: yes, 2012
In this paper, we estimate the third and the fourth order central moments for the difference of the Lupas, q-analogue of the Bernstein operator and the limit q-Lupas, operator. We also prove a quantitative variant of Voronovskaja's theorem for R-n,R-

The Surprise Examination Paradox and the Second Incompleteness Theorem [PDF]

open access: yes, 2010
We give a new proof for Godel's second incompleteness theorem, based on Kolmogorov complexity, Chaitin's incompleteness theorem, and an argument that resembles the surprise examination paradox.

The generalization of some results for Schurer and Schurer-Stancu operators

open access: yesJournal of Numerical Analysis and Approximation Theory, 2011
In the present paper we generalize some results for Schurer and Schurer-Stancu operators. Firstly, we establish a general formula concerning calculation of test functions by Schurer operators.

A Theorem on Preference Aggregation [PDF]

open access: yes
I present a general theorem on preference aggregation. This theorem implies, as corollaries, Arrow's Impossibility Theorem, Wilson's extension of Arrow's to non-Paretian aggregation rules, the Gibbard-Satterthwaite Theorem and Sen's result on the ...

A Unifying Impossibility Theorem [PDF]

open access: yes
This paper considers social choice correspondences assigning a choice set to each non-empty subset of social alternatives. We impose three requirements on these correspondences: unanimity, independence of preferences over infeasible alternatives and ...

On the order of convergence of Voronovskaja-type formulas [PDF]

open access: yes, 2010
In this work general quantitative estimates of Voronovskaja-type formulas in the space of functions of several variables that are twice continuously differentiable and in the space of functions with weighted second-order derivatives are ...
