Let (D={(x,y):x^{2}+y^{2}\le 1}). For a given $n$-point set (P\subset D), write [ m(P):=\min_{{p,q,r}\subset P}\operatorname{Area}(\triangle pqr). ] Your (\alpha(n)) is exactly the extremal quantity [ \alpha(n)=\sup_{|P|=n,P\subset D} m(P), ] i.e. the **largest possible value of the smallest triangle area** forced amon…
