Optional Stopping: Xmas Drinks (Long Sleeve)

$26.94
The Brownian Christmas tree again, this time at the office party. A barrier stands to one side, and every random walk that reaches it stops right there, under a stop sign. The walks that never get that far carry on to the bottom. Even the snowdrift stops at the line. That is a stopping time: a rule for when to stop that depends only on what has happened so far. You may stop when you reach your limit; you may not stop because you have peeked at tomorrow's hangover. In the jargon, it must be measurable in your filtration — and so, the shirt insists, must the xmas drinks. The heading is the real thing. The Optional Stopping Theorem is a cornerstone of martingale theory, and the reason nobody beats a fair game by choosing cleverly when to leave the table. The drinks, as the name suggests, are optional. For quants, probabilists, anyone who has sat through a course on stochastic processes, and anyone who knows when to call it a night. Printed in full colour. Printed on a Bella+Canvas Supersoft long-sleeve tee: lightweight, exceptionally soft, with a smooth print surface. Unisex fit. Dark-shirt version — white artwork, shown on darker garment colours.
