Abstract
An intrinsic characterization of self-adjoint $C^\ast $-Segal algebras among Banach $\ast $-algebras is obtained in terms of Pták’s spectral function. A connection between order structure in $C^\ast $-Segal algebras and Grothendieck’s well known dual characterization of $C^\ast $-algebras is revealed.
