Hello  
Are there packages for computing multipliers of limit cycles? I know about that i can calculate Poincare map with package DynamicalSystems, but how can i get multipliers of limit cycles?

Thank you!  
Can you share example of how to calculate this with a package?

It depends on how your PO is defined, and found. This computation is set automatically in BK. Have you looked at the tutorials?

In my case i don’t change parameter. I have limit cycle in phase space and want calculate for him multipliers of limit cycle
