报告摘要:
Celestial amplitude plays an important role in the understanding of holography. Computing celestial amplitudes by recursion can deepen our understanding of the structure of celestial amplitudes. As an important recursion method, Berends-Giele (BG) current on the celestial sphere is worth studying. In this talk, I will review the definition of celestial amplitudes first and then introduce the celestial BG recursion. I will also utilize this to calculate some typical examples. Moreover, I will introduce how to generalize the ``sewing procedure" for BG currents to the celestial case.
