Classification of Links of Small Complexity in the Thickened Torus
We present a complete table of links in the thickened torus T2 × I of complexity at most 4. The table is constructed by the following method. First, we enumerate all abstract quadrivalent graphs with at most four...

Tabulating knots in the thickened Klein bottle
We tabulate all knots in the oriented thickened Klein bottle having diagrams with three crossings and less. For proving that the knots are distinct, we use a generalization of the Kauffman bracket polynomial i...

Classification of Knots of Small Complexity in Thickened Tori
We present a table of knots in a thickened torus T × I the diagrams of which have less than five crossing points. The knots are constructed by a three-step process: enumeration of regular graphs of degree 4, e...

Construction and Properties of the t-Invariant
Special spine theory is used for constructing a new invariant of compact 3-manifolds: the t-invariant. The behavior of the invariant under (boundary) connected sum is investigated. One of the Turaev―Viro invarian...

On a simple invariant of Turaev-Viro type
For 3-manifolds, we define an invariant t(M)=a+bε, where a,b are integers and \(\varepsilon = (1 \pm \sqrt 5 )/2\) ....

A Hausdorff space which, under any topological imbedding into an arbitrary Hausdorff space Y, is a closed set in Y. The characteristic property of an H-closed space is that any open covering of the space contains...
