The Hermite function expansions of the Heaviside function. (English) Zbl 1315.33014

Summary: We calculate the coefficients of Hermite function expansions of the Heaviside functions, \(x^{p}_{+}\) with \(p\in \mathbb {N}\), \(\frac{1}{x\pm i0}\), the signum \(\operatorname{sgn}(x)\) and the principal value p.v.\(\frac{1}{x}\), explicitly.
