Abstract: A bstractUsing the N$$ \mathcal{N} $$ = 4, 1D harmonic superspace approach, we construct a new type of N$$ \mathcal{N} $$ = 4 supersymmetric mechanics involving 4n-dimensional Quaternion-Kähler (QK) 1D sigma models as the bosonic… read more here.

Abstract: We classify non-polar irreducible representations of connected compact Lie groups whose orbit space is isometric to that of a representation of a finite extension of $$\mathsf{Sp}(1)^k$$Sp(1)k for some $$k>0$$k>0. It follows that they are obtained… read more here.
