Knots and links in three dimensional flows The closed orbits of three dimensional flows form knots and links. This book develops the tools template theory and symbolic dynamics needed for studying knotted orbits. This theory is applied to the problems of understanding local and global bifurcations as well as the embedding data of orbits in Morse smale Smale and integrable Hamiltonian flows. The necesssary background theory is sketched; however some familiarity with low dimensional topology and differential equations is assumed
