A Formula Relating Entropy Monotonicity to Harnack Inequalities
∣ 2 u dV. This implies in particular that d dt μ(g(t), τ(t)) ≥ 0 with equality exactly for homothetically shrinking solutions of Ricci flow. An important consequence of this entropy formula is a lower volume ratio bound for solutions of Ricci flow on a closed manifold for a finite time interval [0, T ) asserting the existence of a constant κ > 0, only depending on n, T and g(0), such that the i...
متن کاملRelating Turing's Formula and Zipf's Law
An asymptote is derived from Turing's local reestimation formula for population frequencies, and a local reestimation formula is derived from Zipf's law for the asymptotic behavior of population frequencies. The two are shown to be qualitatively different asymptotically, but nevertheless to be instances of a common class of reestimation-formula-asymptote pairs, in which they constitute the uppe...
متن کاملRelating Polynomial Time to Constant Depth
Going back to the seminal paper [FSS84] by Furst, Saxe, and Sipser, analogues between polynomial time classes and constant depth circuit classes have been considered in a number of papers. Oracles separating polynomial time classes have been obtained by diagonalization making essential use of lower bounds for circuit classes. In this note we show how separating oracles can be obtained uniformly...
متن کاملRelating Computation and Time
Consider any action y 00 in this set. Since y 00 2 B 00 x , we have x 00 y 00. It now remains to be shown that y 00 2 Before(y). Suppose y 00 6 2 Before(y). Then x 0 y 00 (because x 0 y 0). Consequently, y 00 2 B 0 x which also contradicts the selection of y 00. So y 00 2 Before(y). if: Consider instants t = (A; B) and t 0 = (A 0 ; B 0) such that t < t 0. We show that Suppose that the condition...
متن کاملRelating road salt to exceedances of the water quality standard for chloride in New Hampshire streams.
Six watersheds in New Hampshire were studied to determine the effects of road salt on stream water quality. Specific conductance in streams was monitored every 15 min for one year using dataloggers. Chloride concentrations were calculated from specific conductance using empirical relationships. Stream chloride concentrations were directly correlated with development in the watersheds and were i...
