In this note we show that a weakly geometrically flat map $π$ : M $\rightarrow$ N between pure dimensional complex spaces has the local lifting property for cycles. From this result we also deduce that, under these hypotheses, several properties of M are transferred to N.
The aim of this book is to show that the use of f-analytic families of finite type cycles (cycles having finitely many irreducible components, but not compact in general) in a given complex space may be useful in complex geometry, despite the fact that the corresponding functor is not, in general, representable, in contrast to the compact case. This study leads to the notion of strongly quasi-proper map which is characterized by the existence of a geometric f-flattening which is a generalization of the Geometric Flattening Theorem for proper holomorphic maps. As applications we prove an existence theorem for meromorphic quotients of reduced complex spaces and a generalization of the classic Stein factorization.
