Tony Chapman,Bill Best,Paul Van Casteren in mathematics. Christoffel, highly appreciated in Zurich as teacher and researcher, was the organizer of the school of mathematics and sciences. Well aware of the importance of Riemann’s work, he used his influence to obtain the appointment of Prym, a young student of Riemann. Both left the school

Martin J. Conyon,Joachim Schwalbach. B. Christoffel’s appointment and his occupations at the Gewerbeakademie. Chr. P. W. Beuth, the reknown reformer and organizer of Prussian polytechnical education, founded the “Technisches Institut” in 1821. This institution changed names twice, and in 1879 (then called Gewerbeakademie) it merged w

The main tools are the approximation properties of ., developed by Christoffel, together with the hypothesis that .(.) should satisfy a first-order differential equ

It is shown that these approximants are all also defined by the generating function method. For . ≥ ., our Chebyshev series approximants are equal to the Clenshaw-Lo
