Explicit modified Euler approximations of the Aït-Sahalia type model with Poisson jumps
This paper focuses on mean-square approximations of a generalized Aït-Sahalia interest rate model with Poisson jumps. The main challenge in the construction and analysis of time-discrete numerical schemes is caused by a drift that blows up at the origin, highly nonlinear drift and diffusion coefficients and positivity-preserving requirement. Due to the presence of the Poisson jumps, additional difficulties arise in recovering the exact order $1/2$ of convergence for the time-stepping schemes. …

is it just me, or did keyboard controls for video players stop working on macOS Safari a while ago? pressing k or space to pause works, but pressing again just jumps forward one frame or something instead of resuming. disabling all content blockers doesn't help & having the same problem on Nebula oO
EDIT: it was just me! I had the StopTheMadness For Web Apps extension active!
