Abstract :
In this paper, we introduce the concept strong algebrability of certain 𝐶∗
algebras generated by finite generators. In fact, using Gelfand theorem, we
identify the members of the 𝐶∗ algebra generated by one element, with the
continuous functions on its spectrum, and use some recent result for strong
algebrability for functions spaces. Moreover, we introduce the new concept
unitable elements in unital 𝐶∗ algebras, and then we express our main result
for this kind of elements. In fact, the 𝐶∗ subalgebra generated by a non unitable
element in a 𝐶∗ algebra is strongly 𝑐 algebrable. As the last result in this paper,
we show 2𝑐 strong algebrability of direct sums of 𝐶∗ algebras, using non
unitable elements of them.
