A Banach space B has the
Dunford-Pettis property if xn∗(xn) → 0 whenever xn→ 0 weakly and the sequence
xn∗ tends to zero weakly in B∗ (i.e. σ(B∗,B∗∗)). Suppose now that A is a uniform
algebra on a compact space X. If ϕ is a nonzero multiplicative linear functional on A
then Mϕ is the set of positive representing measures of ϕ. If A is such that a singular
measure which is orthogonal to A must necessarily be zero and if all Mϕ are weakly
compact sets then the algebra A as well as its dual have the Dunford-Pettis
property.
