Almost-prime $k$-tuples [PDF]

open access: yesarXiv, 2012
Let $k\ge 2$ and $\Pi(n)=\prod_{i=1}^k(a_in+b_i)$ for some integers $a_i, b_i$ ($1\le i\le k$). Suppose that $\Pi(n)$ has no fixed prime divisors. Weighted sieves have shown for infinitely many integers $n$ that $\Omega(\Pi(n))\le r_k$ holds for some integer $r_k$ which is asymptotic to $k\log{k}$.

On the Origin of the Laff er Curve [PDF]

open access: yesACTA VŠFS, 2019
In 1974 Arthur Laffer sketched his famous curve on a restaurant napkin. Jude Wanniski gave the curve Laffer’s name and popularized it in 1978. Nowadays the Laffer curve is part of most economics textbooks and essential argument in tax debates.

Bounded length intervals containing two primes and an almost-prime II [PDF]

open access: yesarXiv, 2013
Zhang has shown there are infinitely many intervals of bounded length containing two primes. It appears that the current techniques cannot prove that there are infinitely many intervals of bounded length containing three primes, even if strong conjectures such as the Elliott-Halberstam conjecture are assumed.

Fortschritt und Arbeitszeit: Ein Vergleich der Ansichten von Marx, Keynes und der Sozialdemokratie

open access: yesMomentum Quarterly, 2014
Die Ideen von Karl Marx und John Maynard Keynes übten im Laufe der Zeit großen Einfluss auf die Ansichten der österreichischen Sozialdemokratie aus. Beide Autoren sahen das Ziel der Geschichte in der Selbstverwirklichung des Menschen.

Large gaps between primes [PDF]

open access: yesarXiv, 2014
We show that there exists pairs of consecutive primes less than $x$ whose difference is larger than $t(1+o(1))(\log{x})(\log\log{x})(\log\log\log\log{x})(\log\log\log{x})^{-2}$ for any fixed $t$. Our proof works by incorporating recent progress in sieve methods related to small gaps between primes into the Erdos-Rankin construction. This answers a well-

Validity of the economic thoughts of Keynes and Marx for the 21st century [PDF]

open access: yesZbornik radova Ekonomskog fakulteta u Rijeci : časopis za ekonomsku teoriju i praksu, 2007
This paper examines the validity of economic thoughts of Karl Marx and John Maynard Keynes for the present time. The paper compares Marx and Keynes, and aims to show that the difference in treatment of the major economic issues between them is not as ...
