Streaking field purely for shock and entertainment value or political purposes. The first known instance of streaking in cricket took place on 22 March 1974, the first day of the third test between Australia and New Zealand at Auckland. Half an hour before the end of the day's play, while New Zealand was batting, "a dark-haired young man" ran from near the sightscreen, through mid-wicket and disappeared between the stands near the square-leg boundary. The incident occurred quickly and police did not have time to react. Reports differ on whether the man was completely naked, with some accounts stating that he
Principal ideal theorem Principal ideal theorem In mathematics, the principal ideal theorem of class field theory, a branch of algebraic number theory says that extending ideals gives a mapping on the class group of an algebraic number field to the class group of its Hilbert class field, which sends all ideal classes to the class of a principal ideal. The phenomenon has also been called "principalization", or sometimes "capitulation". For any algebraic number field "K" and any ideal "I" of the ring of integers of "K", if "L" is the Hilbert class field of "K", then is a principal ideal α"O", for "O"
