This insures that the multiplication operation is continuous. |
:(i.e., the norm of the product is less than or equal to the product of the norms.) This ensures that the multiplication operation is continuous. |
Several elementary functions which are defined via [power series]? may be defined on any Banach algebra; examples include the exponential function and the trigonometric function. |
