Submaximally Symmetric Quaternion Hermitian Structures
Boris Kruglikov, Henrik Winther
We consider and resolve the gap problem for almost quaternion-Hermitian structures, i.e. we determine the maximal and submaximal symmetry dimensions, both for Lie algebras and Lie…

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 .…
