Canonical orderings and their relatives such as st-numberings have been used as a key tool in algorithmic graph theory for the last decades. Recently, a unifying link behind all these orders has been shown that links them to well-known graph decompositions into parts that have a prescribed vertex-connectivity. Despite extensive interest in canonical orderings, no analogue of this unifying conce...

let $g$ be a finite group and let $gk(g)$ be the prime graph of $g$. we assume that $ngeqslant 5 $ is an odd number. in this paper, we show that the simple groups $b_n(3)$ and $c_n(3)$ are 2-recognizable by their prime graphs. as consequences of the result, the characterizability of the groups $b_n(3)$ and $c_n(3)$ by their spectra and by the set of orders of maximal abelian subgroups are obtai...

the reptile's fauna of sabzevar was investigated during 10 years (2003-2013). in total 43 species belonging to 29 genera, 13families and two orders (squamata and testudines) were collected and identified. the most diverse group in the area is lizards with 23 species, followed by snakes with 18 species and the testudines with one species. the most diverse families are colubridae , lacertidae wit...

The feminist adage “the personal is political” not ahistorical. It being operationalized in a time when the relationship between private and public undergoing historic transformation. Making privatized violence under current conditions often involves channeling most authoritarian tendencies of state into relationships made increasingly desperate by contemporary capitalism. ethnographic focus es...
