| Abstract: | In this paper,the problem of characterization in approximation by a group of sets of linearly constrainted polynomials is approached.Clear and concrete results are achieved consequently in uniform approximation by polynomial sets of locally convex cone and by polynomial sets with multiply restricted renges of their derivatives. |

| Keywords: | Approximation characterization linear constraintion locally convex cone restricted ranges of derivatives |
