Webapplications of knot theory to modern chemistry, biology and physics. Introduction to Knot Theory - Feb 10 2024 Knot theory is a kind of geometry, and one whose appeal is very direct because the objects studied are perceivable and tangible in everyday physical space. It is a meeting ground of such diverse branches of mathematics as group theory, WebJul 25, 2024 · Knots and representation theory are deeply intertwined. Here's one example. In classical representation theory, one aspect of Schur-Weyl duality is that every endomorphism of $V^ {\otimes n}$ that commutes with the $SL (V)$ action can be written as a linear combination of permutations.

WebFeb 10, 2016 · — You may not have heard of knot theory. But take it from Bill Menasco, a knot theorist of 35 years: This field of mathematics, rich in aesthetic beauty and intellectual challenges, has come a long way since he got into it. It involves the study of mathematical knots, which differ from real-world knots in that they have no ends.

While inspired by knots which appear in daily life, such as those in shoelaces and rope, a mathematical knot differs in that the ends are joined so it cannot be undone, the simplest knot being a ring (or "unknot").
