Abstract: | In this talk we introduce a Weierstrass-like system of equations corresponding to CP
N
-1 fields in two dimensions. Then using this representation we introduce a vector in R
N
2-1 and treating this vector as the radius vector of a surface immersed in R
N
2-1 we discuss to what extent the associated metric describes the geometry of the CP
N
-1 maps. We show that for the holomorphic maps - the correspondence is exact; while for the more general fields we have to go
beyond the Weierstrass system and add extra terms.
