　　内容简介：

　　In this presentation, Prof Yu is anxious to share his recent findings from studying temporal universe. He proposes one model that is quite different from Newtonian space-time and also somewhat different from Hawking's universe.

　　Based on Einstein’s energy equation, he shows that energy and mass can be traded and every mass can be treated as an Energy Reservoir. Since physical space cannot be embedded in an absolute empty space, our universe is fully packed with physical substances. He explains how it takes time to create a physical space (e.g., our universe) and it cannot bring back the time as had been used for the creation. This means that the origin of our universe was created by time with a gigantic explosion, in which every substance coexists with time. Without time, the creation of all physical substances would not have happened. Although time ignited the creation, yet it is the created physical substances. Moreover, we present a new approach to low-rank tensor completion when the number of samples is only slightly more than the dimension of the corresponding manifold, by solving a set of polynomial equations using Newton’s method.  In many applications, sampled data are sent to a central cloud server to complete the tensor completion task. However, revealing data to the server raises privacy concerns. To that end we propose a novel framework for privacy-preserving tensor completion, called homomorphic tensor completion, that is relatively easy to implement in practice.in practice.

　　Moreover, Prof Yu will describe his most recent research findings and shows that Schrödinger’s radio-active particle is timeless or time-independent. But a timeless particle cannot exist within a temporal subspace. Therefore, the paradox of Schrödinger's Cat, after all is not a paradox at all.
