His topics include varieties over arbitrary fields, faithfully flat descent, algebraic groups, cohomological
obstructions to rational points, and surfaces.
These fermionic and bosonic symmetries (and corresponding charges) provide the physical realizations of the de Rham cohomological
operators of differential geometry whereas discrete symmetry plays the role of Hodge duality (*) operation (see, e.g., [16-18] for details).
A kind of Borsuk-Ulam type theorems consists in estimating the cohomological
dimension of the set A(f,H, G).
Now, we state a cohomological
criterion for k-summability of formal series with coefficients in Banach spaces (see , p.
(1) Any principal homogeneous space (torsor) under a connected linear algebraic group G defined over k, which satisfies the cohomological
Hasse principle over each global subfield contained in k.

Pure spinor superfields were developed with the purpose of covariant quantization of superstrings by Berkovits [4-7] and the cohomological
structure was independently discovered in supersymmetric field theory and supergravity, originally in the context of higher-derivative deformations [8-17].
