Finite groups have even more centralizers
For a finite group $G$, let $Cent(G)$ denote the set of centralizers of single elements of $G$. In this note we prove that if $|G|leq frac{3}{2}|Cent(G)|$ and $G$ is 2-nilpotent, then $Gcong S_3, D_{10}$ or $S_3times S_3$. This result gives a partial and positive answer to a conjecture raised by A. R. Ashrafi [On finite groups with a given number of centralizers, Algebra Collo...

متن کاملScaling laws in cognitive sciences.
Scaling laws are ubiquitous in nature, and they pervade neural, behavioral and linguistic activities. A scaling law suggests the existence of processes or patterns that are repeated across scales of analysis. Although the variables that express a scaling law can vary from one type of activity to the next, the recurrence of scaling laws across so many different systems has prompted a search for ...
متن کاملCeteris Paribus Laws and the Human Sciences
In opposition to the traditional conception of scientific laws as universal and exceptionless generalizations that hold everywhere and throughout all times, some philosophers of science have proposed the idea of a ceteris paribus law (CP law), i.e., a law that is true " all else being equal " , in the sense that it can admit of exceptions because of the influence of interfering factors. The leg...
متن کاملMajorana ’ s article on “ The value of statistical laws in physics and social sciences ”
This article was found by Majorana’s brother among Ettore Majorana’s files and was published in 1942 after Majorana’s disappearance in the international Italian journal Scientia. It is a rather special article in several respects. It was intended to present the point of view of a physicist about the value of statistical laws in physics and social sciences to scholars of a broad spectrum of diff...
