Algebraic Maximal Numerical Range and its preservers of Triple Products on $C^{*}$ -Algebras

Yongqi Fan, Xiaofei Qi, Jinchuan Hou

The paper investigates the algebraic maximal numerical range in unital C*-algebras and characterizes surjective maps that preserve this range for triple products, showing they are…
