On intrinsic normalizations of semi-non-holonomic hypercomplexes SNGr(1, n, 2n-3) in affine space

Lietuvos Matematikos Rinkinys, 1998
In this paper the differential geometry of semi-non-holonomic hypercomplexes in n-dimensional affine space is constructed in an invariant analytic form. The differential neighbourhoods of first two orders are studied.

Normal Coordinates in Affine Geometry [PDF]

Учёные записки Казанского университета: Серия Физико-математические науки, 2017
Manifolds of affine geometry of general type with nontrivial metric, torsion, and nonmetricity tensor have been considered. These manifolds have recently attracted much interest due to the construction of generalized gravity models.

Geometry of the spectral parameter and renormalisation of integrable sigma-models

Journal of High Energy Physics
In the past few years, the unifying frameworks of 4-dimensional Chern-Simons theory and affine Gaudin models have allowed for the systematic construction of a large family of integrable σ-models.
