Abstract

The \$k\$-core percolation on the Bethe lattice has been proposed as a simple model of the jamming transition because of its hybrid first-order/second-order nature. We investigate numerically \$k\$-core percolation on the four-dimensional regular lattice. For \$k=4\$ the presence of a discontinuous transition is clearly established but its nature is strictly first order. In particular, the \$k\$-core density displays no singular behavior before the jump and its correlation length remains finite. For \$k=3\$ the transition is continuous.
