Random walk with heterogeneous sojourn time
Jaywan Chung, Yong-Jung Kim, Min-Gi Lee
We introduce a discrete-time random walk model on a one-dimensional lattice with a nonconstant sojourn time and prove that the discrete density converges to a solution of a continu…

Convergence and Divergence of Approximations in terms of the Derivatives of Heat Kernel
Jaywan Chung
We consider an approximate solution to the heat equation which consists of the derivatives of heat kernel. Some conditions in the initial value, under which the approximation conve…
