Correction: Because of reporting errors, a story in Sunday’s Arts section misstated the given name of the Merce Cunningham Trust’s Robert Swinston and mischaracterized the dancers who will perform Cunningham’s “How to Pass, Kick, Fall and Run’’ this summer at the Institute of Contemporary Art. They are students at the Juilliard School and Tufts.

Correction: Because of a reporting error, a story on the Nation pages in Sunday’s paper about the arrests of three men in Chicago on terrorism charges gave conflicting dates for the arrest. The men were arrested Wednesday.

Correction: Because of editing errors, an incorrect photo accompanied the G Force column in Monday’s “g’’ section about Dr. Jordan Smoller. The correct photo is shown here.
