About this symbol
The filled square at the end of a proof means “which was to be shown”, a modern stand-in for the Latin Q.E.D., quod erat demonstrandum. The American mathematician Paul Halmos brought it into mathematics from magazines, which used a small block to mark the end of an article, so it is often called the Halmos or tombstone.
