Crosscap numbers of 2-bridge knots
Mikami Hirasawa, Masakazu Teragaito
We present a practical algorithm to determine the minimal genus of non-orientable spanning surfaces for 2-bridge knots, called the crosscap numbers. We will exhibit a table of cros…

Constructions of Morse maps for knots and links, and upper bounds on the Morse-Novikov number
Mikami Hirasawa, Lee Rudolph
The Morse-Novikov number MN(L) of an oriented link L in the 3-sphere is the minimum number of critical points of a Morse map from the complement of L in the 3-sphere to the circle…

Almost alternating diagrams and fibered links in S^3
Hiroshi Goda, Mikami Hirasawa, Ryosuke Yamamoto
Let be an oriented link with an alternating diagram . It is known that is a fibered link if and only if the surface obtained by applying Seifert's algorithm to i…
