The authors study the eigenvalues of nonselfadjoint linear differential operators which smoothly depend on a vector of real parameters. They present formulas for bifurcations of multiple eigenvalues with Keldysh chains of arbitrary length along smooth curves in the space of parameters. Stability conditions for distributed circulation systems are analyzed.
