On $I$ and $I^*$-Cauchy conditions in $C^*$-algebra valued metric spaces

Amar Kumar Banerjee, Anirban Paul


The idea of $C^*$-algebra valued metric spaces was given by  Ma, Jiang and Sun. In this paper we have studied the ideas of $I$-Cauchy and $I^*$-Cauchy sequences and their properties in such spaces and also we give the idea of $C^*$-algebra valued normed spaces.


$C^*$-algebra valued metric space, $C^*$-algebra valued normed space, $I$-convergent, $I$-Cauchy, $I^*$-Cauchy.
