# Latex union of sets

Hi, I have actually what I hope is a really basic question related to unfamiliar notation. I am looking via a maths paper on a topic pertained to set theory which contains a symbol,

$uplus$,

and also I would certainly favor to recognize just how, if at all, it differs from the typical

$cup$

symbol in regards to its meaning. The conmessage leads me to think that it does not in fact differ at all however given that I do not even recognize the name of the symbol other than the latex id that I looked up, I can"t seem to confirm that suspicion. Cheers

edit: it appears that the latex renderer additionally does not know about this obscure symbol "cupplus" however "uplus" does occupational.

You watching: Latex union of sets

edit2: thanks for all the replies! however, given that everyone commented fairly than providing a solution it appears I cannot give the coveted "answer" status to anyone. the disjoint union renders the a lot of feeling.

For the sake of offering an answer to tag as an answer:

Some authors usage this to denote a disjoint union of sets, i.e., "$A cup B$ for sets $A, B$ wbelow $A cap B = emptyset$."

It might likewise represent that the union is a multi-collection (and also the both operands are probably multi-sets). Then the multiplicity of an element in the outcome is the amount of its multiplicities in the operands, that describes the existence of the + in the symbol.
