Speaker: Prof. Chao Zhou (National University of Singapore)Venue: Room 203, Building 2, Haina Court, Zijingang CampusAbstract: This paper deals with the optimization problem of a class of controlled N-particle systems. We establish the regularity results, which is uniform in N , on the HJB equations corresponding to the N-particle system. The uniform regularity results are obtained by the stochastic maximum principle and the analysis on a Riccati type BSDE. Using the uniform regularity results, we show the convergence of value function and optimal control as the number N of particles tends to infinity, where the convergence rates are also given. This is based on a joint work with Huafu Liao, Alpar Meszaros and Chenchen Mou.Contact person: Prof. ZHANG Rongmao (rmzhang@zju.edu.cn)

Speaker: Prof. HUANG Qihai (University of Huddersfield)Host: Prof. HU Qiongjing (Zhejiang University)Venue: Room 723, Building A, School of Management, Zijingang CampusAbstract: Online labor platforms (OLPs) employ algorithmic management practices to manage app-workers. Drawing upon the self-determination theory, this research examines the impact of perceived algorithmic management practices (PAMP) on the service performance of ride-hailing drivers through three studies. We theorise the process by investigating the mediating roles of individual needs satisfaction (competence, autonomy, and relatedness) and work engagement, and the moderating role of online community support (OCS). We developed and validated a PAMP scale using a rigorous multistep process in the first study. In the second study, we empirically tested our conceptual model with a sample of 431 ride-hailing drivers. Our findings reveal that PAMP influences drivers’ competence, autonomy, and relatedness needs satisfaction differently. The satisfaction of these three basic needs enhances work engagement, subsequently improving service performance.Furthermore, OCS positively moderates the relationship between PAMP and drivers’ needs satisfaction. To deepen our understanding of how PAMP influences drivers’ needs satisfaction and subsequent behaviors, we conducted a qualitative investigation with 103 ride-hailing drivers. Our study provides valuable insights for future research and practice in managing app-workers in the gig economy.

Speaker: Prof. CHEN Yanze (University of Alberta)Venue: Room 101, Building 2, Haina Court, Zijingang CampusAbstract: An analogue of the Segal-Shale-Weil representation for loop symplectic groups over a local field was constructed by Zhu 15 years ago. For a reductive dual pair in a symplectic group over a global field, one can thus consider the analogue of the global theta lifting of an automorphic form in the context of loop groups. We computed the theta liftings of a "cusp form" on the loop GL(n) group induced from a "classical" cusp form for the loop group dual pair (GL(n),GL(n)), and explained the result an Eisenstein series. In this computation, an interesting model of the local loop Weil representation is introduced, which is essentially due to Kapranov. This is a joint work with Yongchang Zhu.Contact person: Prof. LIU Dongwen (maliu@zju.edu.cn)

Speaker: Prof. Zhimin ShiVenue: Online (Zoom ID: 851 7706 1692)Abstract:The first part of the talk is centered around understanding and utilizing high-dimensional light, also known as structured light. I will first present a family of direct tomography protocols that can characterize various types of structured light or high-dimensional photon states. I will introduce some high-performance mode sorters for structured light as well as a series of scan-free direct tomography protocols that can measure high-dimensional spatial modes, spatial vector modes and partially-coherent modes (mixed states). The direct tomography methods directly relate the readouts to the complex-valued description of the photon states to be measured, and can measure the entire photon state in a single experimental setup without any need of scanning. Consequently, direct measurements become critical in enabling real-time metrology of both quantum and classical photon states. I will will present some recent work on robust high-information-capacity optical communication protocols in turbulent environment, including a turbulence-resilient vector beam based communication protocol, a phase conjugation based scheme to enable communication using OAM modes with low crosstalk through a 340m free-space-link, and a vector phase conjugation scheme that can enable 210-spatial-polarization mode communication through 1 km of multi-mode fiber. These breakthroughs can lead to practical carryout of high-dimensional optical communications in realistic environment. The second part of the talk is to introduce Meta’s vision and efforts to empower people to connect with each other and the world around them. In specific, I will present some collective work from Reality Labs – Research to address one question: “What will we need for future VR’s display?”Profile of the speaker: Zhimin Shi received his Ph.D. degree in Optics from the University of Rochester in 2011. Before that, he received his Bachelor and M.S. degree in Optical Engineering, both with honors, from Zhejiang University in 2001 and 2004, respectively. He was a faculty position at the Department of Physics, The University of South Florida from 2013 to 2020. He then joined Meta Reality Labs – Research and currently is a technical lead manager working on new optical and photonic technologies to enable future AR/VR systems. His research interests include integrated photonics, metamaterials, displays, quantum state metrology, imaging and communication with structured light, slow and fast light, and optical techniques using nonclassical nature of light. Dr. Shi is a senior member of Optica (formerly OSA) , a life member of SPIE, and also currently serves as a topical editor for the Journal of Optical Society of America A.
