The purpose of the pro ject is to study properties of groups of birational automorphisms of algebraic varieties on the level of their finite subgroups. Basically, I want to deal with two issues: general structure theorems about finite birational automorphism groups, and conjugacy classes of finite subgroups of groups of birational automorphisms. ... Another thing that is of certain interest about finite groups of birational automorphisms is the structure of conjugacy classes. ...

... The overall globular cluster population is divided by gap in the metallicity function at [Fe/H]=-1.0 into two discrete groups with well-defined maxima at [Fe/H]=-1.60?0.03 dex, and -0.60?0.04 dex. ... Clusters with extremely blue horizontal branches occupy a spherical volume of radius ~ 9 kpc, have high rotational velocities ( V rot =77?33 km/s), have substantial and equal negative radial and vertical metallicity gradients, and are, on average, the oldest group (the old-halo subsystem). ...
