There are still many other answers that no answer in the "Answer" is formulated. I feel that an answer should alway include the full statement of its result explicitly. Preferably, most of the time, an answer should start with the explicit full statement of its result. | |

Made some statements more precise, in particular my "no"

| Jun 18, 2016 at 8:57 | comment | added | Todd Leason | @Yemon Choi: I read it this way: The OP asks if a unit is necessary for the existence of an equivalent multiplicative norm and Duchamp Gérard H. E.s answer says "No, a unit is not necessary - such norm always exists". | |
| Jun 17, 2016 at 21:17 | comment | added | Yemon Choi | I don't understand: I thought the answer to the given question is yes. Certainly we in BA world believe that if one has a Banach space, equipped with an algebra product that is continous, then this space can be renormed with an equivalent norm such that one gets a Banach algebra in the usual sense. | |
