Abstract

Let (X,ω)(X,\omega) be a compact K\"{a}hler manifold with a K\"{a}hler form ω\omega of complex dimension nn, and VXV\subset X is a compact complex submanifold of positive dimension k<nk<n. Suppose that VV can be embedded in XX as a zero section of a holomorphic vector bundle or rank nkn-k over VV. Let φ\varphi be a strictly ωV\omega|_V-psh function on VV. In this paper, we prove that there is a strictly ω\omega-psh function Φ\Phi on XX, such that ΦV=φ\Phi|_V=\varphi. This result gives a partial answer to an open problem raised by Collins-Tosatti and Dinew-Guedj-Zeriahi, for the case of K\"{a}hler currents. We also discuss possible extensions of K\"ahler currents in a big class.
