I'm having trouble understanding the following sentence from Schutz's A First Course in General Relativity, so I was hoping someone could explain/expound on it. "
p_a \equiv \widetilde{p}( \vec{e_{\alpha} ) } ) Any component with a single lower index is, by convention, the component of a one-form; an upper index denotes the component of a vector."
