Bernstein-type inequalities for splines defined on the real axis

We obtain exact Bernstein-type inequalities for splines s ? S_m,h?L₂( \mathbbR ) s \in {S_{m,h}}\bigcap {{L_2}\left( \mathbb{R} \right)} , as well as the exact inequalities estimating, for splines s ∈ S _{m, h} , h > 0; the L _p -norms of the Fourier transforms of their kth derivative in terms of the L _p -norms of the Fourier transforms of the splines themselves.
