Sharp connectivity bounds for the vacant set of random interlacements

Subhajit Goswami, Pierre-François Rodriguez, Yuriy Shulzhenko

We consider percolation of the vacant set of random interlacements at intensity in dimensions three and higher, and derive lower bounds on the truncated two-point function for…

An operatorial approach of the well-posedness of an algebraic Riccati equation

Gabriela Marinoschi

Finding the state feedback control in an -optimal control problem involves a challenging approach of the associated algebraic Riccati equation of the generic form $A…
