Exponential stabilization of the solution for time dependent neutron transport equation (Q1898900)

The authors consider the time-dependent neutron transport equation in \(\mathbb{R}^3\) [\textit{K. Jörgens}, Commun. Pure Appl. Math. 11, 219-242 (1958; Zbl 0081.441)]\ and using a previous result [\textit{C. V. Pao}, J. Integral Equations 1, No. 2, 131-152 (1979; Zbl 0441.45014)]\ they give a sufficient condition for its solution to decay exponentially as the time variable goes to infinity.
