The Boltzmann Transport Equation can be expressed in operator notation by
$$M\phi=\lambda F\phi$$
or
$$(M-\lambda F)\phi=0$$
$M$ is the neutron loss operator. F is the fission operator, and $\lambda$ is the eigenvalue of the system. where $\lambda=\frac{1}{k_{eff}}$
[[Fission Operator]] – F
[[Adjoint Flux Equation]] – adjoint version of the boltzmann transport equation
