Query: Multi-Point Virtual Structure Constants and Mirror Computation of
  CP^2-model   In this paper, we propose a geometrical approach to mirror computation of
genus 0 Gromov-Witten invariants of CP^2. We use multi-point virtual structure
constants, which are defined as intersection numbers of a compact moduli space
of quasi maps from CP^1 to CP^2 with 2+n marked points. We conjecture that some
generating functions of them produce mirror map and the others are translated
into generating functions of Gromov-Witten invariants via the mirror map. We
generalize this formalism to open string case. In this case, we have to
introduce infinite number of deformation parameters to obtain results that
agree with some known results of open Gromov-Witten invariants of CP^2. We also
apply multi-point virtual structure constants to compute closed and open
Gromov-Witten invariants of a non-nef hypersurface in projective space. This
application simplifies the computational process of generalized mirror
transformation.
