The elliptic KZB connection and algebraic de Rham theory for unipotent fundamental groups of elliptic curves
In this paper, we develop an algebraic de Rham theory for unipotent
fundamental groups of once punctured elliptic curves over a field of
characteristic zero using the universal elliptic KZB connection of
Calaque-Enriquez-Etingof and Levin-Racinet. We use it to give an explicit
version of Tannaka duality for unipotent connections over an elliptic curve
with a regular singular point at the identity.Comment: minor revisions on introduction, and on section 7 where the result is

Nuclear dependence asymmetries in direct photon production
We study the nuclear dependences of high- jet cross sections in one
photon and one jet production in proton-nucleus collisions. We find that there
exist asymmetries between the outgoing jets and photons. A convincing reason
responsible for those asymmetries are demonstrated in perturbative QCD.
Significant nuclear enhancements are also found in the inclusive jet cross
sections.Comment: 9 pages, LaTeX, 5 ps-figure
Learning to Generate Time-Lapse Videos Using Multi-Stage Dynamic Generative Adversarial Networks
Taking a photo outside, can we predict the immediate future, e.g., how would
the cloud move in the sky? We address this problem by presenting a generative
adversarial network (GAN) based two-stage approach to generating realistic
time-lapse videos of high resolution. Given the first frame, our model learns
to generate long-term future frames. The first stage generates videos of
realistic contents for each frame. The second stage refines the generated video
from the first stage by enforcing it to be closer to real videos with regard to
motion dynamics. To further encourage vivid motion in the final generated
video, Gram matrix is employed to model the motion more precisely. We build a
large scale time-lapse dataset, and test our approach on this new dataset.
Using our model, we are able to generate realistic videos of up to resolution for 32 frames. Quantitative and qualitative experiment results
have demonstrated the superiority of our model over the state-of-the-art
models.Comment: To appear in Proceedings of CVPR 201
