We perform the gauge-fixing of the theory of a chiral two-form boson in six
dimensions starting from the action given by Pasti, Sorokin and Tonin. We use
the Batalin-Vilkovisky formalism, introducing antifields and writing down an
extended action satisfying the classical master equation. Then we gauge-fix the
three local symmetries of the extended action in two different ways.Comment: 15 pages, latex, no figures, version accepted by Class. Quant. Gra
