Erratum to: Almost complex structures in 6D with non-degenerate Nijenhuis tensors and large symmetry groups
Boris Kruglikov, Henrik Winther
We correct an error in the second part of Theorem 3 of our original paper (arXiv:1512.07161).
Integrability via geometry: dispersionless differential equations in three and four dimensions
David M. J. Calderbank, Boris Kruglikov
We prove that the existence of a dispersionless Lax pair with spectral parameter for a nondegenerate hyperbolic second order partial differential equation (PDE) is equivalent to th…
Non-degenerate Para-Complex Structures in 6D with Large Symmetry Groups
Boris Kruglikov, Henrik Winther
For an almost product structure on a manifold of dimension with non-degenerate Nijenhuis tensor , we show that the automorphism group has dimension at…
Reconstruction from Representations: Jacobi via Cohomology
Boris Kruglikov, Henrik Winther
A subalgebra of a Lie algebra determines -representation on . In this note we discuss ho…
Submaximally Symmetric Almost Quaternionic Structures
Boris Kruglikov, Henrik Winther, Lenka Zalabova
The symmetry dimension of a geometric structure is the dimension of its symmetry algebra. We investigate symmetries of almost quaternionic structures of quaternionic dimension .…
On the symmetry algebras of 5-dimensional CR-manifolds
Alexander Isaev, Boris Kruglikov
We show that for a real-analytic connected holomorphically nondegenerate 5-dimensional CR-hypersurface and its symmetry algebra one has either: (i) $\dim\mathfra…
