Bessel and Grüss type inequalities in inner product modules over Banach \(\ast \)-algebras
This interesting paper may be regarded as a continuation of the previous work of the same authors [Linear Algebra Appl. 434, No.~4, 944--956 (2011; Zbl 1218.46027)]. They give further generalizations of Grüss type inequalities as well as Bessel type inequalities in inner product modules over proper \(H^*\)-algebras, \(C^*\)-algebras and unital Banach \(*\)-algebras. The interested reader is referred to \textit{S. Banić} and \textit{D. Ilišević} [Proc. Edinb. Math. Soc., II. Ser. 50, No.~1, 23--36 (2007; Zbl 1160.46038)] and \textit{S. S. Dragomir}, \textit{M. Khosravi} and \textit{M. S. Moslehian} [Linear Multilinear Algebra 58, No.~7--8, 967--975 (2010; Zbl 1210.46043)] for other results in this context.
