Using a novel theoretical approach, we study the mean first-encounter time (MFET) between the two ends of a polymer. Previous approaches used various simplifications that reduced the complexity of the problem, leading, however, to incompatible results. We construct here for the first time a general theory that allows us to compute the MFET. The method is(More)
In [11] an example presented a Hausdorff continuous, u.s.c. and l.s.c. multifunction from 〈−1, 0〉 to R which had no continuous selection. The multifunction was not locally Lipschitz. In this paper we show that a locally Lipschitz multifunction from R to a Banach space, which has ”locally finitely dimensional“ closed values does have a continuous selection.
