Abstract

We prove in this note a result on extension of meromorphic mappings, which can be considered as a direct generalisation of the Hartogs extension theorem for holomorphic functions. Namely: THEOREM. Every meromorphic mapping f:Hnq(r)Yf:H_n^q(r)\to Y, where YY is a qq - -complete complex space, extends to a meromorphic mapping from Δn+q\Delta^{n+q} to YY. Here Hnq(r):=Δn×(ΔqΔˉrq)Δrn×ΔqH_n^q(r):=\Delta^n\times (\Delta^q\setminus \bar\Delta_r^q)\cup \Delta_r^n\times \Delta^q is a "q-concave" Hartogs figure in Cn+qC^{n+q}. Remark that in the case q=1q=1, i.e. when YY is Stein, the statement of the Theorem is exactly the Theorem of Hartogs.
