Bridge-index conjecture for discrete Morse vectors of knots
Bridge-index conjecture for discrete Morse vectors of knots
Let be a knot with bridge index . Say that a -complex has discrete Morse vector if it admits a discrete Morse function with exactly critical faces of dimension . Bridge-index conjecture. The knot appears in both of the following ways:
- As a knotted spanning edge in some -ball with discrete Morse vector , if .
- As a -edge subcomplex of some -sphere with discrete Morse vector , if .
The claim is presented as a conjectural consequence suggested by the knot-theoretical approach, relating bridge index to the minimum number of critical faces in a discrete Morse function. Its resolution is not specified in the supplied text.
