(I'll be here till Tuesday.) Evidently, the symbol you are using for "such that" is being shown on my screen as a small rectangle. In the copy below, I see two rectangles before the A=, two before the B=, two after the A, two after the B. The UNION symbol (inverted "U") shows up but is followed by a rectangle in the next two examples and preceded by a rectangle in the last three. In checking a table of logic notaion, I find that the relation "such that" is designated by a reversed capital "E". Is this the symbol you are using? m.a. ----- Original Message ----- From: Bruno Marchal To: everything-list@googlegroups.com Sent: Saturday, June 06, 2009 4:36 PM Subject: Re: The seven step-Mathematical preliminaries 2
We do have problem of symbols, with the mail. I don't see any rectangle in the message below! Take it easy and . We will go very slowly. It will also be the exam periods. There is no rush ...
