| 摘 要： | In this paper we show that the unit ball of an infinite dimensional commutative C^*-algebra lacks strongly exposed points, so they have no predual. Also in the second part, we use the concept of strongly exposed points in the Frechet differentiability of support convex functions.

| Abstract: | In this paper we show that the unit ball of an infinite dimensional commutative C*-algebra lacks strongly exposed points, so they have no predual. Also in the second part, we use the concept of strongly exposed points in the Frechet differentiability of support convex functions.
