Yu. K. Dem'yanovich, D. M. Lebedinskii, N. A. Lebedinskaya St. Petersburg State University, St. Petersburg, Russia
Abstract:
Two-sided estimates of continuously differentiable coordinate splines of the second order are established, and sufficient conditions of their nonnegativeness are provided. The results obtained are applied to trigonometric splines.
Key words and phrases:
coordinate splines, two-sided estimates, generating vector function, components of a representation, local quasi-equidistant grid.
