Minimal time control for the heat equation with multiple impulses
This paper investigates a minimal time control problem for the heat equation with multiple impulse controls. We first establish the maximum principles for this problem and then prove the equivalence between the minimal time impulse control problem and its corresponding minimal norm impulse control problem. Extending our analysis to the minimal time function itself, we examine its analytical properties (particularly continuity and monotonicity) with respect to the control constraint. This leads …

I was a baseball fan when I was a kid and for the first time in 32 years my home team is in the hilariously misnamed World Series. I am consequently paying for a sports streaming package for the first time in my life. I feel very strange about this, like I have crossed some threshold of stereotypical adult masculinity.

Monday's excellent adventure: business in NYC M-F, need to take the train. Not yet packed, chores-chores-chores around the house, train to catch at 2pm. At 12:29 I am still home, need to drop by work to drop off some stuff and then catch the red line to South Station to the Acela. So at 12:30 I hop on the cargo bike, assist to maximum, arrive at work 25 minutes later, leave bike in the "long term" parking, drop crap at desk, I have a few minutes to grab lunch,

I'm not sure how to interpret "Of those, more than 80% (57,000) have earned initial approvals but have not yet received the final sign-off from the Department of Building Inspection to begin construction."
Are they confounding Planning approval - general building form issues such as lot coverage, height, number of bedrooms, parking minimum/maximum, bicycle storage, etc - with DBI permit approval, which gets into the construction details - issues of structural integrity, f…

Toxic haze chokes Indian capital
India's capital New Delhi was shrouded in a thick, toxic haze on Monday as air pollution levels soared to more than 16 times the World Health Organization's recommended daily maximum.

Maximum principle for discrete-time robust stochastic optimal control problem
This paper firstly presents the necessary and sufficient conditions for a kind of discrete-time robust stochastic optimal control problem with convex control domains. As it is an "inf sup problem", the classical variational method is invalid. We obtain the variational inequality with a common reference probability by systematically using weak convergence approach and the minimax theorem. Moreover, a discrete-time robust investment problem is also studied where the explicit optimal control is gi…

Maximum principle for robust utility optimization via Tsallis relative entropy
This paper investigates an optimal consumption-investment problem featuring recursive utility via Tsallis relative entropy. We establish a fundamental connection between this optimization problem and a quadratic backward stochastic differential equation (BSDE), demonstrating that the value function is the value process of the solution to this BSDE. Utilizing advanced BSDE techniques, we derive a novel stochastic maximum principle that provides necessary conditions for both the optimal consumpti…
