The versal deformation of small resolutions of conic bundles over ${\mathbb{P}}^1\times {\mathbb{P}}^1$ with two sections blown down

Bernd Kreussler, Jan Stevens

Twistor spaces are certain compact complex threefolds with an additional real fibre bundle structure. We focus here on twistor spaces over $3\mathbb{C}{\mathbb{P}}^2$. Such spaces ar…
