Ward identities in the Toda conformal field theory
Baptiste Cerclé, Yichao Huang
Toda conformal field theories are natural generalizations of Liouville conformal field theory that enjoy an enhanced level of symmetry. In Toda conformal field theories this higher…
Another probabilistic construction of in dimension 2
Yichao Huang
The main input of this note is to provide an alternative probabilistic approach to the theory in dimension 2, based on concentration phenomenon of martingales associated t…
Path integral approach to analytic continuation of Liouville theory: the pencil region
Yichao Huang
We study the problem of analytic continuation of Liouville Conformal Field Theory using the probabilistic approach of David, Kupiainen, Rhodes and Vargas [DKRV16] based on the theo…
Two perspectives of the 2D unit area quantum sphere and their equivalence
Juhan Aru, Yichao Huang, Xin Sun
2D Liouville quantum gravity (LQG) is used as a toy model for 4D quantum gravity and is the theory of world-sheet in string theory. Recently there has been growing interest in stud…
Liouville Quantum Gravity on the unit disk
Yichao Huang, Rémi Rhodes, Vincent Vargas
Our purpose is to pursue the rigorous construction of Liouville Quantum Field Theory on Riemann surfaces initiated by F. David, A. Kupiainen and the last two authors in the context…
Random Beamforming with Heterogeneous Users and Selective Feedback: Individual Sum Rate and Individual Scaling Laws
Yichao Huang, Bhaskar D. Rao
This paper investigates three open problems in random beamforming based communication systems: the scheduling policy with heterogeneous users, the closed form sum rate, and the ran…
Joint Beamforming and Power Control in Coordinated Multicell: Max-Min Duality, Effective Network and Large System Transition
Yichao Huang, Chee Wei Tan, Bhaskar D. Rao
This paper studies joint beamforming and power control in a coordinated multicell downlink system that serves multiple users per cell to maximize the minimum weighted signal-to-int…
Multicell Random Beamforming with CDF-based Scheduling: Exact Rate and Scaling Laws
Yichao Huang, Bhaskar D. Rao
In a multicell multiuser MIMO downlink employing random beamforming as the transmission scheme, the heterogeneous large scale channel effects of intercell and intracell interferenc…
Performance Analysis of Heterogeneous Feedback Design in an OFDMA Downlink with Partial and Imperfect Feedback
Yichao Huang, Bhaskar D. Rao
Current OFDMA systems group resource blocks into subband to form the basic feedback unit. Homogeneous feedback design with a common subband size is not aware of the heterogeneous c…
An Analytical Framework for Heterogeneous Partial Feedback Design in Heterogeneous Multicell OFDMA Networks
Yichao Huang, Bhaskar D. Rao
The inherent heterogeneous structure resulting from user densities and large scale channel effects motivates heterogeneous partial feedback design in heterogeneous networks. In suc…
