... In electron-positron colliders, effect of the lattice modification by opposing bunch focusing on the equilibrium radiation emittance is important at high values of the space charge parameter, so one should correctly evaluate this dynamic radiation emittance of the weak beam, which may differ a lot from the nominal emittance, already in the linear beam-beam force model. ... The linearized beam-beam force is equivalent to focusing insertion in linear lattice of the collider. ...

... The zeta function of the classical monodromy transformation of the germ $f$ is a topological invariant of it. Let us consider a parametrization (uniformization) of the curve $(C,0)$. The order of a function on $(C,0)$ as a function in the uniformization parameter defines a decreasing filtration on the ring of functions on the curve singularity. It appears that the Poincare series of this filtration (considered as a rational function) coincides with the zeta function mentioned above. ...
