Prime knots whose arc index is smaller than the crossing number
Gyo Taek Jin, Hwa Jeong Lee
It is known that the arc index of alternating knots is the minimal crossing number plus two and the arc index of prime nonalternating knots is less than or equal to the minimal cro…
Modeling network technology deployment rates with different network models
Yoo Chung
To understand the factors that encourage the deployment of a new networking technology, we must be able to model how such technology gets deployed. We investigate how network struc…
Singular values of principal moduli
Ja Kyung Koo, Dong Hwa Shin
Let be a principal modulus with rational Fourier coefficients for a discrete subgroup of between or for a positive integer . Le…
On simple labelled graph -algebras
Ja A Jeong, Sun Ho Kim
We consider the simplicity of the -algebra associated to a labelled space $(E,\CL,\bE)$, where $(E,\CL)$ is a labelled graph and $\bE$ is the smallest accommodating set contai…
Yang-Mills Instantons from Gravitational Instantons
John J. Oh, Chanyong Park, Hyun Seok Yang
We show that every gravitational instantons are SU(2) Yang-Mills instantons on a Ricci-flat four manifold although the reverse is not necessarily true. It is shown that gravitation…
