# How can I decrease the space between the symbol “<” and text?

I use "0<F<1" in Latex, however in the pdf it is "0 < F < 1 ", I want to reduce the space between text and <, just like "0<F<1", would someone tell me how to do it?

Why do you want to do this? This introduces inconsistency in your document. – Gonzalo Medina Aug 13 '12 at 17:40

0{<}F{<}1

An alternative in math mode is to use negative spaces defined by \!. Each one will backshift characters by 1/6 quad.
