Popis:	The domain D ( δ 2 ) of the square of a closed ∗-derivation δ in C ( K ) (K is a compact Hausdorff space) is a generalization of the space C ( 2 ) [ 0 , 1 ] . In this paper, we determine extreme points of D ( δ 2 ) 1 ∗ and the structure of surjective linear isometries of D ( δ 2 ) with some graph norm.
