Tech support told me how to fix the problem.

 

I am using Tomcat that is installed originally with Mac OS X Server 10.6.

There seems to be a problem with 64bit version of jvm.

In order to fix the problem, /Library/Tomcat/bin/startup.sh should be rewitten as follows;

 

exec "$PRGDIR"/"$EXECUTABLE" start "$@"

->

export JAVA_OPTS=-d32

exec "$PRGDIR"/"$EXECUTABLE" start "$@"

 

Thank you for Tech support !

Hello, I think how long dsolve calculates for the complex ODE depends on K1 and K2. What complex constants did you choose ? I would like to try to solve it. When you cast the ODE into a system of 2 ODEs, did you get a solution for long time ? Yasuyuki Nakamura

Hi, I have a Maplet application for fourier series, fourier_series.mw. If you want, you can download it from http://thomas.phys.cs.is.nagoya-u.ac.jp/. On that page, there is a link for fourier_series.mw. Best wishes, Yasuyuki Nakamura
