# What is Boas: Definition and 38 Discussions

Luís André de Pina Cabral e Villas-Boas (Portuguese pronunciation: [luˈiz‿ɐ̃ˈdɾɛ ðɨ ˈpinɐ kɐˈβɾaɫ i ˈvilɐʒ ˈboɐʃ]; born 17 October 1977), known as André Villas-Boas, is a Portuguese football manager, who most recently was the manager of Ligue 1 club Marseille. He is one of a growing number of top-level managers who have never played football professionally and one of the few managers to have never played beyond youth football.Highlights in his career include an undefeated 2010–11 season in the Primeira Liga with Porto, winning four trophies and becoming the youngest manager ever to win a European title in the process, helping Tottenham to their then-record tally of 72 points in the Premier League during the 2012–13 season (the highest points for a team to finish outside the top four at the time) and three trophies during his spell with Zenit, achieving the fifth league title in the club's history.

22. ### Exploring Mary Boas' Theorem III: Analytic Functions & Taylor Series

On page 671 Mary Boas has her Theorem III for that chapter. Roughly it tells us that if f(z) -a complex function- is analytic in a region, inside that region f(z) has derivatives of all orders. We can also expand this function in a taylor series. I get the part about a Taylor series, that's...

In Boas' book I can read that the definition of center of mass of a body has coordinates x_{CM}= \int x_{CM}dM= \int x dM. Shouldn't it be this same integral but divided by M?! Also, I didn't find the definition of center of mass for particles or any non continuous bodies. I'd be grateful if...
