The Schwarz reflection principle: if U = U∗, and f is analytic on U∩H, continuous and real on the boundary, then f(z) extends f to all of U. This is easy from Morera’s theorem. A better version only requires WebbIn this article, we established new results related to a 2-pre-Hilbert space. Among these results we will mention the Cauchy-Schwarz inequality. We show several applications related to some statistical indicators as average, variance and standard deviation and correlation coefficient, using the standard 2-inner product and some of its properties.
