Let $(\mathfrak{g}, \{J_{\alpha}\})$ be a nilpotent hypercomplex Lie algebra. Here, $\mathbb{H}$-solvability means that the descending $\mathbb{H}$-central series defined by…

A hypercomplex structure $(X,I,J,K)$ is exotic if $(X,I)$ is holomorphically symplectic, but for no choice of $\alpha \in \operatorname{Kahl}(X)$ does the corresponding hyperkähler…

Maximal-time conjecture. There exists a unique maximal solution to the adapted Chern–Ricci flow on $[0,T)$.
