 Abstract
We show that every Jordan functional on a Banach algebra A is continuous. From this result we obtain that every Jordan mapping from A into a continuous function space C(S) is continuous and it's norm less than or equal where S is a compact Hausdorff space. This is a generalization of Jarosz's result [3, Proposition 5.5].
