Explicit birational geometry of threefolds of general type

Jungkai A. Chen, Meng Chen

Let $V$ be a complex nonsingular projective 3-fold of general type. We prove $P_{12} (V) > 0$ and $P_{24} (V) > 1$ (which answers an open problem of J. Kollar and S. Mori). We also prove…

The canonical volume of threefolds of general type with $χ < 1$

Jungkai A. Chen, Meng Chen

We prove that the canonical volume $K^{3} \geq 1/30$ for all projective 3-folds of general type with $χ (O) \leq 0$ . This bound is sharp.
