I was reading a text where I found the expression
Take an integral commutative $\mathbb{C}$-algebra.
It' doesn't give a definition so I don't know what it means for $\textbf{integral}$. Now I don't know if it means that the algebra is an integral domain as a ring or if it is integrally closed. Hence I want to ask if there is a standard definition of integral commutative $\mathbb{C}$-algebra.
thanks in advance.
