Classification of genus two knots which admit a (1,1) decomposition
Mario Eudave-Muñoz, Fabiola Manjarrez-Gutierrez, Enrique Ramirez-Losada
We describe the genus two knots which admit a genus one, one bridge position. These are divided into several families, one consists of vertical bandings of two genus one -kn…
Hyperbolic (1,2)-knots in S^3 with crosscap number two and tunnel number one
Luis G. Valdez-Sanchez, Enrique Ramirez-Losada
A knot in S^3 is said to have crosscap number two if it bounds a once-punctured Klein bottle but not a Moebius band. In this paper we give a method of constructing crosscap number…
On finite index subgroups of a universal group
G. Brumfiel, H. Hilden, M. T. Lozano +5
The orbifold group of the Borromean rings with singular angle 90 degrees, , is a universal group, because every closed oriented 3--manifold occurs as a quotient space $M…
Meridional surfaces and (1,1)-knots
Mario Eudave-Munoz, Enrique Ramirez-Losada
We determine all (1,1)-knots which admit an essential meridional surface, namely, we give a construction which produces (1,1)-knots having essential meridional surfaces, and show t…
