The 5-canonical system on 3-folds of general type
Jungkai A. Chen, Meng Chen, De-Qi Zhang
Let be a projective minimal Gorenstein 3-fold of general type with canonical singularities. We prove that the 5-canonical map is birational onto its image.

The Noether inequality for smooth minimal 3-folds
Fabrizio Catanese, Meng Chen, De-Qi Zhang
Let X be a smooth projective minimal 3-fold of general type. We prove the sharp inequality K^3_X >= (2 /3)(2p_g(X) - 5), an analogue of the classical Noether inequality for algebra…

A Nonvanishing Theorem for Q-divisors
Jungkai Alfred Chen, Meng Chen, De-Qi Zhang
We prove a non-vanishing theorem of the cohomology H^0 of the adjoint divisor K_X + L' where L' is the round up of a nef and big Q-divisor L.
