I'm stuck, what does ~ denote?
Y and ~Y, where ~Y does read as ... ?
Not-Y, i.e. Y is false..
I see, thank you. Does it add too much noise if I ask such questions, should I rather not yet read the sequences if I sometimes have to inquire about such matters? Or should I ask somewhere else?
I was looking up this table of mathematical symbols that stated that ~ does read as 'has distribution' and stopped looking any further since I'm dealing with probabilities here. I guess it should have been obvious to me to expect a logical operator. I was only used to the notation not and ¬ as the negation of a proposition. I'll have to adjust my perceived intelligence downwards.
Others that gets used a lot in various contexts are !Y, Y^c (for Y complement). There are probably more, but I can't think of them at the moment.
Y with a bar over it also gets used (though be careful as this more commonly means closure of Y, or, well, quite a few other things...)
No, these are reasonable questions to ask.
There's no problem with asking a clarifying question like that, which might help other lurkers and can be answered quickly without huge amounts of work.
By the way, there's no need for such self-deprecating comments about your education or intelligence. It's socially a bit off-putting to talk about the topic, and it risks coming across as disingenous. Just ask your questions without such supplication.
