Abstract
Motivated by invalidness of Liouville property for harmonic functions on the
connected sum $\#^\vartheta\mathbb C^m$ with $\vartheta\geq2,$ we study
Nevanlinna theory on a complete K\"ahler connected sum $$M=M_1\#\cdots\# M_\vartheta$$ with $\vartheta$ non-parabolic ends. Based on
the global Green function method, we extend the second main theorem of
meromorphic mappings to $M.$ As a consequence, we obtain a Picard's little
theorem provided that all $M_j^,s$ have non-negative Ricci curvature, which
states that every meromorphic function on $M$ reduces to a constant if it omits
three distinct values.In particular, it implies that Cauchy-Riemann equation
supports a rigidity of Liouville property as an invariant under connected sums.
