## Abstract Let __d__ΞΌ(__x__) = (1 βˆ’ __x__^2^)^Ξ±βˆ’1/2^__dx__,Ξ±> βˆ’ 1/2, be the Gegenbauer measure on the interval [ βˆ’ 1, 1] and introduce the non‐discrete Sobolev inner product where Ξ»>0. In this paper we will prove a Cohen type inequality for Fourier expansions in terms of the polynomials orthogona
