| Abstract: | In this paper we introduce a new kind of Birkhoff type interpolation of functions with period 2 . We find necessary and sufficient conditions for regularity of this new interpolation problem. Moreover, a closed form expression for the interpolation polynomial is given.This work was supported by China State Major Key Project for Basic Researchers. |
