A version of Carleman’s formula summation of the Riemann ζ -function on the critical line [PDF]

open access: yesМатематичні Студії, 2011
A version of Carleman's formula for functions holomorphic in a rectangle is proved. It is applied to the evaluation of the integral of ζ -function logarithm with the summing factor exp(−t) along the critical line.

Equivalent teleparallel theories in diagonalizable spacetimes: Comment on "Metric-affine approach to teleparallel gravity"

open access: yes, 2013
It is well known that the teleparallel equivalent of general relativity yields the same vacuum solutions as general relativity does, which ensures that this particular teleparallel model is in good agreement with experiments. A less known result concerns

Riedizioni e riemissioni di periodici nel contesto editoriale italiano: XVII secolo-1805. Esempi e osservazioni

open access: yesTECA, 2011
The paper shows some ways of publishing Italian journals from XVII century to early years of ‘800. It contains large set of exemples of important titles issued again as monographics in context without ties with journalism yet; some reprints are also ...

The Kervaire-Laudenbach conjecture and presentations of simple groups

open access: yes, 2004
The statement ``no nonabelian simple group can be obtained from a nonsimple group by adding one generator and one relator" 1) is equivalent to the Kervaire--Laudenbach conjecture; 2) becomes true under the additional assumption that the initial ...

On problems of the lens of the eye radiation dose monitoring

open access: yesРадиационная гигиена, 2016
According to results of in-depth studies, the risk of the radiation-induced cataract is higher than it was considered earlier. In April 2011, ICRP released a statement on the tissue reactions.

On the density and the structure of the Peirce-like formulae [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
Within the language of propositional formulae built on implication and a finite number of variables $k$, we analyze the set of formulae which are classical tautologies but not intuitionistic (we call such formulae - Peirce's formulae).

Partition Problems and a Pattern of Vertical Sums [PDF]

open access: yes, 2017
We give a possible explanation for the mystery of a missing number in the statement of a problem that asks for the non-negative integers to be partitioned into three subsets.

Though Forced, Still Valid: Psychometric Equivalence of Forced-Choice and Single-Statement Measures [PDF]

open access: yesOrganizational Research Methods, 2019
Forced-choice (FC) measures are gaining popularity as an alternative assessment format to single-statement (SS) measures. However, a fundamental question remains to be answered: Do FC and SS instruments measure the same underlying constructs? In addition, FC measures are theorized to be more cognitively challenging, so how would this feature influence

W$^*$-superrigidity for coinduced actions

open access: yes, 2018
We prove W$^*$-superrigidity for a large class of coinduced actions. We prove that if $\Sigma$ is an amenable almost-malnormal subgroup of an infinite conjugagy class (icc) property (T) countable group $\Gamma$, the coinduced action $\Gamma ...

Monotone Picard Maps in Relational Metric Spaces

open access: yesMathematics
The 2008 fixed point result on rs-relational metric spaces due to Jachymski is equivalent with the classical 1922 Banach Contraction Principle. This is also valid for the 1961 statement in metric spaces due to Edelstein, or the 2005 fixed point result in
