Abstract
We study the matter part of the algebra of open string fields using the 3-string vertex over the sliver state, which we call ``comma vertex''. By generalizing this comma vertex to the -string overlap, we obtain a closed form of the Neumann coefficients in the -string vertex and discuss its relation to the oscillator representation of wedge states.
