Millennium problems! Help.

Dear all,

I'm an artist working on projects concerning maths.

I'm working on a conceptual work about what are considered the "Millennium problems" and I'm looking for excerpts of demonstration regarding those unsolved maths problems. Where could I find any written attempt of solution? I just need some writing that would symbolize each problem, still something that would make sense.

The problems are :

1.Birch and Swinnerton-Dyer Conjecture

2.Hodge Conjecture

3.Navier-Stokes Equations

4.P vs NP

5.Poincaré Conjecture

6.Riemann Hypothesis

7.Yang-Mills Theory

Anyone can help?
