Transactions of the American Mathematical Society, Vol. 367, No. 5 (MAY 2015), pp. 3481-3508 (28 pages) In this paper we show that the fields of rational invariants over the irreducible components of ...

Set theory serves as a foundational pillar in mathematics, providing the language and tools necessary to discuss infinite collections. A central focus within this discipline is the study of cardinal ...

Knot theory, a vibrant branch of topology, investigates the properties of knots viewed as embeddings of circles in three-dimensional space. Central to this field are knot invariants—algebraic or ...
