Tempers flare as 20 Hong Kong villagers lose homes to Northern Metropolis Hundreds of security guards and police officers deployed to evict Tin Sam Tsuen villagers, despite residents saying concerns remain largely unresolved Hundreds of security guards and police officers were deployed on Tuesday to evict about 20 residents from a Hong Kong village as part of the government’s Northern Metropolis blueprint, despite residents saying their concerns remain largely unresolved. The operation by...
Hong Kong should adopt the ‘Hefei model’ in the Northern Metropolis
The arrival of Yuan Gujie, the new deputy director of Beijing’s liaison office in Hong Kong, has sparked widespread speculation. Her legal background and experience in Guangdong province suggest that her posting carries a clear agenda: to promote deeper integration between Hong Kong and other Greater Bay Area cities. One thing is clear: if the Northern Metropolis is to accelerate, Hong Kong’s existing legal framework and development model may prove inadequate.
University town to set aside land to capitalise on future social, tech changes
University town to set aside land to capitalise on future social, tech changes Education minister Christine Choi says university town, which falls under Northern Metropolis, to have distinctive Hong Kong characteristics A proposed university town in Hong Kong will set aside vacant land to capitalise on future opportunities arising from social and technological changes, a minister has said, days after a top official revealed that the project size could be tripled to 300 hectares (741 acres)....
A geometric $q$-analogue of Hamiltonian Monte Carlo
arXiv:2512.13246v3 Announce Type: replace Abstract: Hamiltonian Monte Carlo (HMC) generates efficient Markov transitions by combining Hamiltonian dynamics with a Metropolis correction. This paper develops a geometric \(q\)-analogue of HMC by replacing classical Hamiltonian dynamics with a \(q\)-deformed Hamiltonian system arising from \(q\)-calculus. Starting from a Lagrangian formulation, we derive the corresponding \(q\)-Hamiltonian equations and prove the formal invariance of the...
Self-Certifying Transport MCMC via Dual Spectral-Gap Certificates
arXiv:2605.30722v2 Announce Type: replace Abstract: We propose CerT-MCMC, a framework that equips learned-transport Markov chain Monte Carlo with automatic, rigorous convergence certificates. A normalising flow maps a Gaussian reference to an approximation of the target posterior; the same flow then serves as both the independence Metropolis-Hastings proposal and the basis for a computable spectral-gap bound. We develop two complementary certificates.
Non-Vacuous Certification of Transport MCMC via Oscillation-Controlled Normalizing Flows
arXiv:2606.01078v1 Announce Type: new Abstract: Transport MCMC trains a normalizing flow to precondition Metropolis--Hastings proposals, achieving high empirical efficiency on challenging posteriors; yet no prior work produces a numerically non-vacuous, rigorous spectral-gap bound for such samplers. We establish the first such bounds. For independence MH on the banana family we certify (\gamma^\ast = 0.828) at (D = 2) (covering in the original space) and (\gamma^\ast \ge 7.6\times 10^{-4})...
Lantau reclamation plans should be revived, property tycoon Gordon Wu says
Hong Kong should revive plans for large-scale reclamation off Lantau Island to run in parallel with the Northern Metropolis project, property magnate Gordon Wu Ying-sheung has said, warning that a lack of urban land will hold back the city’s development as the population grows. The 90-year-old founder and chairman of Hopewell Holdings also described it as “too early to say” whether his property empire would follow its peers and commit to investing in the mega development near the city’s...

Hong Kong authorities propose doubling size of planned Lau Fau Shan tech hub
Hong Kong authorities have proposed doubling the size of a planned digital technology hub in Lau Fau Shan under the city’s Northern Metropolis megaproject, while landmark buildings would be permitted to reach up to about 250 metres (820 feet) in height under the initiative. The amended proposal, which will be discussed by the Yuen Long District Council’s town planning and development committee on Thursday, seeks to expand the digital technology hub from 15 to 30 hectares (6.07 to 12.14...
