Abstract: | The associativity anomaly in the star algebra of the open bosonic string is demonstrated by a simple oscillator calculation. In an associative algebra, formal arguments require that the “half string” BRST operator QL be nilpotent; however, we show that associativity is actually violated by computing QL2 in an explicit operator representation of the star algebra. |
