On the relation between the non-commuting graph and the prime graph [PDF]
International Journal of Group Theory, 2012 Given a non-abelian finite group $G$, let $pi(G)$ denote the set of prime divisors of the order of $G$ and denote by $Z(G)$ the center of $G$. Thetextit{ prime graph} of $G$ is the graph with vertex set $pi(G)$ where two distinct primes $p$ and $q$ are ...

ON THE GROUPS WITH THE PARTICULAR NON-COMMUTING GRAPHS [PDF]
Journal of Algebraic Systems, 2015 Let $G$ be a non-abelian finite group. In this paper, we prove that $Gamma(G)$ is $K_4$-free if and only if $G cong A times P$, where $A$ is an abelian group, $P$ is a $2$-group and $G/Z(G) cong mathbb{ Z}_2 times mathbb{Z}_2$.

Structural change in the US office market after 2019: Evidence from lease‐level data
Real Estate Economics, EarlyView.Abstract This article examines how the leasing activities, contract features, and pricing of the Class A office leasing market have evolved since 2019 across five major US markets: Los Angeles, the Bay Area, Dallas, Washington, DC, and New York City. Using a granular dataset of 73,508 office leases from 2010 to 2024, we find a broad‐based contraction ...

Globalization, internal migration, and public goods provision in emerging economies
American Journal of Political Science, EarlyView.Abstract Globalization can introduce new employment opportunities to emerging economies in multinational corporations and exporting firms. Who is best positioned to benefit, and what are the political consequences for “left behind” areas? We argue that primarily advantaged groups seize these opportunities through internal migration toward centers of ...

British Journal of Developmental Psychology, EarlyView.Abstract A cross‐sectional study of 106 students (7–12 years) from a rural school in the Brazilian Amazon investigated the interaction among motor, cognitive and environmental factors on school achievement using network analysis. Students with good school performance were significantly older and showed superior global physical fitness, motor ...
