In this work lead and zinc in the soils of permafrost forest-steppe have been studied. It was revealed that binding heavy metals following descending series: Zn > Pb, which corresponds to values their clarks. Studies shown occurs mainly with fulvic acids, -with humic is associated chemical properties. The content Pb rock turned out be lower than soil, possibly due biological accumulation. No...

Bounded local G-shtuka are function field analogs for p-divisible groups with extra structure. We describe their deformations and moduli spaces. The latter are analogous to Rapoport-Zink spaces for p-divisible groups. The underlying schemes of these moduli spaces are affine DeligneLusztig varieties. For basic Newton polygons the closed Newton stratum in the universal deformation of a local G-sh...
