Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In mathematics, the Seifert conjecture states that every nonsingular, continuous vector field on the 3-sphere has a closed orbit. It is named after Herbert Seifert. In a 1950 paper, Seifert asked if such a vector field exists, but did not phrase non-existence as a conjecture. He also established the conjecture for perturbations of the Hopf fibration. The conjecture was disproven in 1974 by Paul Schweitzer, who exhibited a C1 counterexample. Schweitzer''s construction was then modified by Jenny Harrison in 1988 to make a C2 + counterexample for some 0.
