Strict p-negative type of a metric space
Hanfeng Li, Anthony Weston
Doust and Weston introduced a new method called "enhanced negative type" for calculating a non trivial lower bound p(T) on the supremal strict p-negative type of any given finite m…

Optimal lower bounds on the maximal p-negative type of finite metric spaces
Anthony Weston
This article derives lower bounds on the supremal (strict) p-negative type of finite metric spaces using purely elementary techniques. The bounds depend only on the cardinality and…
