【Abstract】 The Birkhoff trigonometric interpolation of π-antiperiodic function was studied,the problem of the π-antiperiodic function(0,P(D)) interpolation on equidistant nodes was solved,the existing conditions of the solution was obtained,the explicit form and the rate of convergence were got in the corresponding condition.更多还原
