The radius of convergence of the Lamé function
Yoon-Seok Choun
We consider the radius of convergence of a Lamé function, and we show why Poincaré-Perron theorem is not applicable to the Lamé equation.
The convergence test to the application in a multi-term recurrence relation of a linear ODE
Yoon-Seok Choun
The recursive relation starts to appear by putting a function into a linear ordinary differential equation (ODE). There can be -term of sequen…
Bridging the Chiral symmetry and Confinement with Singularity
Yoon-Seok Choun, Sang-Jin Sin
We consider a holographic quark model where the confinement is a consequence of the quark condensate. Surprisingly, the equation of motion of our holographic model can be mapped to…
Inexistence of quark mass in chiral symmetry and its relation to confinement dynamics
Yoon-Seok Choun
In 1985, Gürsey showed that the spectrum of the semi-relativistic Hamiltonian for the bag model, introduced by Lichtenberg et al. for mesons, follows the Regge trajectory if the cu…
Chiral symmetry and Heun's equation
Yoon-Seok Choun, Sang-Jin Sin
We show that the current quark mass should vanish to be consistent with the QCD color confinement: a bag model leads us to Heun's equation, which requests that not only the energy…
