Is there a symbol for indicating one vector space is a subspace of another?

[SprucerMoose]

Hi all,

I was just wondering, is there is a particular symbol to say V is a subspace of W?

I suppose V$$\subset$$W works if I describe each (sub)space in set notation first, but I was wondering what I could use if I don't state W or V as a particular set?

Thanks

This depends on which author you read. I think most don't have a notation for it. I always use $$V\leq W$$ however...

My experience is that everybody agrees $$V \leq W$$ is the notation, but nobody bothers using it
