Requests and comments

The definition from formal language seems like it would be a good start. —The preceding unsigned comment was added by 67.30.5.108 (talk • contribs) 09:00, 26 October 2003 (UTC).[reply]

Some examples would also be very nice. —The preceding unsigned comment was added by 131.247.23.72 (talk • contribs) 16:20, 26 June 2007 (UTC).[reply]

On properties of quotients

The previous version incorrectly claimed that a quotient of two context-free languages is context-sensitive.

This is false, any RE set can be constructed in a similar way as the Computation history of a Turing machine can be constructed as an intersection of two context-free languages.
