Stochastic maximum principle for optimal control problem of non exchangeable mean field systems
We study the Pontryagin maximum principle by deriving necessary and sufficient conditions for a class of optimal control problems arising in non exchangeable mean field systems, where agents interact through heterogeneous and asymmetric couplings. Our analysis leads to a collection of forward-backward stochastic differential equations (FBSDE) of non exchangeable mean field type. Under suitable assumptions, we establish the solvability of this system. As an illustration, we consider the linear-q…

It's amazing how many Default Things in normal modern life are the result of nouveau-demi-riche plebs larping whatever inbred brainrot nonsense the aristocracy was doing a century before. Lawns, for example. McMansions. Manners. Golf. The list goes on.

Education Secretary Linda McMahon, in a statement, said Columbia’s leadership
“acted with deliberate indifference towards the harassment of Jewish students on its campus”
and urged the accrediting body to keep the department informed of any actions taken to ensure Columbia’s compliance with accreditation standards.
“Accreditors have an enormous public responsibility as gatekeepers of federal student aid,” McMahon said.
“Just as the Department of Education has an oblig…

A Proximal Variable Smoothing for Minimization of Nonlinearly Composite Nonsmooth Function -- Maxmin Dispersion and MIMO Applications
We propose a proximal variable smoothing algorithm for a nonsmooth optimization problem whose cost function is the sum of three functions including a weakly convex composite function. The proposed algorithm has a single-loop structure inspired by a proximal gradient-type method. More precisely, the proposed algorithm consists of two steps: (i) a gradient descent of a time-varying smoothed surrogate function designed partially with the Moreau envelope of the weakly convex function; (ii) an appli…

The US Secretary of Education, Linda McMahon, seemingly does not know about the 1921 Tulsa Race Massacre or Ruby Bridges:
“I will look into it and get back to you.”
