Baylis and Hushilt pointed out that the Lorentz-Dirac equation with the usual constraint(ẍμ(τ)→0 as τ→∞) for physical solution, may permit two or more solutions to some problems. We impose another constriant to make the physical solution unique.

We point out that the results obtained by Khalili, Mathur and Bodenhorn about the location and production theiry are partially incorrect.We give the precise results and rigorous proofs.

We investigate a general commercial fishing model in this paper. The results imply that fishing capital investiment is non-explosive and fishery resources are non-extinctive.

We give an action integral L(x,X,Aμ,aμ). The stabilities of L against the variations δAμ(ξ),δaμ(ξ),δxμ(θ) and δXμ(τ),give us the coupled Maxwell equations and the Lorentz-Dirac equation for the positron and monopole.
