Relative Entropy in CFT
By using Araki's relative entropy, Lieb's convexity and the theory of
singular integrals, we compute the mutual information associated with free
fermions, and we deduce many results about entropies for chiral CFT's which are
embedded into free fermions, and their extensions. Such relative entropies in
CFT are here computed explicitly for the first time in a mathematical rigorous
way. Our results agree with previous computations by physicists based on
heuristic arguments; in addition we uncover a surprising connection with the
theory of subfactors, in particular by showing that a certain duality, which is
argued to be true on physical grounds, is in fact violated if the global
dimension of the conformal net is greater than Comment: 31 page

Robustness test results.
International crude oil prices has become one of the important factors that affect exchange rate fluctuation. By combining TVP-VAR model and DY time-varying spillover index, this paper measures the two-way fluctuation spillover effect between international crude oil prices and RMB exchange rate from 2011 to 2022. The research results show that: (1) There are obvious time-varying characteristics among international crude oil prices, onshore RMB exchange rate and offshore RMB exchange rate, and they are strengthened when major events occur at home and abroad; (2) The spillover and absorption level among international crude oil prices, onshore RMB exchange rate and offshore RMB exchange rate is relatively limited; (3) After the “exchange rate reform on August 11”, the market participation of RMB exchange rate has increased year by year, and the offshore RMB is mainly net spillover, while the onshore RMB is mainly reflected as a recipient; (4) The offshore RMB exchange rate has a driving effect on the onshore RMB exchange rate. Based on this, it is necessary to orderly promote the development and utilization of new energy, actively promote the market-oriented reform of RMB exchange rate, play the leading role of offshore market, and accelerate the construction of crude oil-RMB settlement system.</div
