Abstract. The present paper is concerned with some representatons of linear mappings of continuous functions into locally convex vector spaces, namely


Theorem. If X is a complete Hausdorff locally convex vector space, then a general form of weakly compact mapping T:C[a,b] → X is of the form Tg=∫abg(t)dx(t), where the function x(⋅):[a,b] → X has a weakly compact semivariation on [a,b].


This theorem is a generalization of the result from Banach spaces to locally convex vector spaces.
