The Final Parsec Problem
The coalescence of massive black hole binaries is one of the main sources of low-frequency gravitational radiation that can be detected by LISA. When two galaxies containing massive black holes merge, a binary forms at the center of the new galaxy. We discuss the evolution of the binary after its separation decreases below one parsec. Whether or not stellar dynamical processes can drive the bla...
متن کاملFinal Report of Special Problem
Projections of global climate change over the next century indicate that multiple stresses to coastal ecosystems are expected. Sea level rise is one effect of climate change that may significantly alter current estuarine habitats, resulting in the need to modify current management strategies. A one dimensional (1D) hydraulic analysis was completed for the Caloosahatchee Estuary to determine the...
متن کاملCranks – Really, the Final Problem
A survey of Ramanujan’s work on cranks in his lost notebook is given. We give evidence that Ramanujan was concentrating on cranks when he died, that is to say, the final problem on which Ramanujan worked was cranks – not mock theta functions.
متن کاملThe Final Value Problem for Sobolev Equations
Let A and B be m-accretive linear operators in a complex Hubert space H with D{A) C D(B). The method of quasi-reversibility is used to obtain a solution to the Sobolev equation (d/dt)[(I + B)u(t)] + Au(t) = 0, 0 < l < 1, which approximates a specified final value u(\) = f. In general, when D(A) C D(B), it is not possible to find a solution which achieves exactly the final value w(l) = /. 1. Let...
متن کاملHandout PFS : Practice Final Solutions 3 Problem
For example, on input a1, a2, a3, a4, a5 where a1 = 3, a2 = 4, a3 = 4, a4 = 5, a5 = 7, a possible solution is to take S1 = {1, 4} and S2 = {2, 3}, bacause a1 + a4 = a2 + a3 = 8. On the other hand, on input the sequence 2, 3, 4, there is no possible solution. Devise a dynamic programming strategy to decide whether such sets S1 and S2 exists. The solution should run in time polynomial in n and M ...
