Title and author in header without fancyhdr

Title and author in header without fancyhdr

I'm trying to have the author names and title appear on alternating pages,
respectively, in the center of the header. In addition I would like to
have even numbered pages on the left in the header and odd numbered pages
on the right in the header - Starting from page 2. I would like to avoid
using the package fancyhdr as I do no want any line separating the header
from the body.
