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\subsetW 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
