Intersection theory on M_{g,n}
I am aware of a Macaulay based program doing this but I am looking for some printed numbers. |

almost holomorphic line bundles
Thanks for sharing your thoughts. I agree with the first paragraph on how the question can be stated. Then in fact, my question is about the existence of a good J_M; generic J_M does not have this property for sure. I am looking for topological or symplectic obstructions against the existence of such J_M. For example, chern class of L is a well-defined 2-form no matter what J is. Then what does the existence of such J impose on this class; if J_M is good, can we conclude that c_1(L) would be (1,1) with respect to J_M? and similar. |

A good metric for transversal intersections
I need to identify a neighborhood of normal bundle with a neighborhood of V in M for some construction to work. |

I was naive, Misha's definition is the rigorous one. |

Thanks for the edit, I was lazy to do that! |

@Taghavi: You special case is OK, but very easy due to your assumptions. |

Being transverse is a property which involves all the manifolds at the same time, transverse manifolds have minimal possible intersection on every subset. |

A good metric for transversal intersections
A transverse set of 3 hypersurfaces in $\mathbb{R}^3$ has only points in their triple intersection. Your example is not a transverse intersection (although every two of them are transverse). |

@ Taghavi: transversal means tangent spaces of different components at a point are in general position, i.e. each group of them has minimum intersection. They might not generate the whole space (e.g to curves in dimension 3) or might not have mutual trivial intersection (e.g surfaces in dim 3). |

all the $V_i$ at the same time Sir! not just $V$. Read the question carefully before you vote to close it. |
