An update on a few permanent conjectures

Fuzhen Zhang (2016)

Special Matrices

Similarity:

We review and update on a few conjectures concerning matrix permanent that are easily stated, understood, and accessible to general math audience. They are: Soules permanent-on-top conjecture†, Lieb permanent dominance conjecture, Bapat and Sunder conjecture† on Hadamard product and diagonal entries, Chollet conjecture on Hadamard product, Marcus conjecture on permanent of permanents, and several other conjectures. Some of these conjectures are recently settled; some are still open.We...

On a special case of Hadwiger's conjecture

Michael D. Plummer, Michael Stiebitz, Bjarne Toft (2003)

Discussiones Mathematicae Graph Theory

Similarity:

Hadwiger's Conjecture seems difficult to attack, even in the very special case of graphs G of independence number α(G) = 2. We present some results in this special case.

On the Collatz conjecture

Sebastian Hebda (2013)

Colloquium Mathematicae

Similarity:

We propose two conjectures which imply the Collatz conjecture. We give a numerical evidence for the second conjecture.
