Abmaj13 is a major 13th with Ab as its root. The full theoretical spelling is Ab, C, Eb, G, Bb, Db, F. This voicing omits the 5th and 9th and 11th, the tones guitarists drop first when fitting a chord onto six strings. A note on 13th chords: the root, 3rd, 7th, and 13th are generally considered sufficient in practice, although the technical definition spells the 9th and 11th as part of the chord too.
