Mazur's knot and the Octahedron

Jack S. Calcut, Yangyang Du

Mazur's knot exterior admits a geometric description using a single regular ideal octahedron. The resulting hyperbolic structure is closely related to the Whitehead link exterior t…

Prime theta-curves on minimal genus Seifert surfaces

Jack S. Calcut, Jamie Phillips-Freedman

We prove that each prime knot union an essential arc on a minimal genus Seifert surface is a prime theta-curve.

Structure and classification of torus theta-curves

Jack S. Calcut, Samantha E. Nieman

We study theta-curves embedded in a standard torus in the 3-sphere. We show that each nontrivial torus knot together with an essential arc determines a prime theta-curve, yielding…

Ends and end cohomology

William G. Bass, Jack S. Calcut

Ends and end cohomology are powerful invariants for the study of noncompact spaces. We present a self-contained exposition of the topological theory of ends and prove novel extensi…

The end sum of surfaces

Liam K. Axon, Jack S. Calcut

End sum is a natural operation for combining two noncompact manifolds and has been used to construct various manifolds with interesting properties. The uniqueness of end sum has be…

Artin presentations, triangle groups, and 4-manifolds

Jack S. Calcut, Jun Li

Gonz{á}lez-Acu{ñ}a showed that Artin presentations characterize closed, orientable -manifold groups. Winkelnkemper later discovered that each Artin presentation determines a smo…
