SUMMARY:Effective integrators for oscillatory second-order initial-value p
 roblems - Xin-Yuan Wu (University of Nanjing)
DTSTART:20120911T140000Z

UID:TALK39705@talks.cam.ac.uk
CONTACT:Dr Shadrin
DESCRIPTION:This talk is to present structure-preserving algorithms for os
 cillatory problems that arise in a wide range of fields such as astronomy\
 , molecular dynamics\, classical mechanics\, quantum mechanics\, chemistry
 \, biology and engineering. Such problems can often be modelled by initial
  value problems of second-order differential equations with a linear term 
 characterizing the oscillatory structure of the systems. Since general-pur
 pose high order Runge-Kutta (RK) methods\, Runge-Kutta-Nystr\\"om (RKN) me
 thods\, and linear multistep methods (LMM) cannot respect the special stru
 ctures of oscillatory problems in long-term integration\, innovative integ
 rators have to be designed. This talk will pay attention to both theories 
 and methods for solving second-order differential equations with oscillato
 ry solutions.\n
