Contributions to the theory of Hermitian series III. Meanvalues

Let f(z) be holomorphic in the strip −σ<y<σ<∞ and satisfy the conditions for having an expansion in an Hermitian series f(z)=∑n=0∞fnhn(z),   hn(z)=(π122nn!)−12e−12z2Hn(z),absolutely convergent in the strip. Two meanvalues 𝔐k(f;y)={π−12∫−∞∞e−kx2|f(x+iy)|2dz}12,   k=0,1.are discussed, directl...
