Thank you for paying attention.

I want to know the meaning of "position-dependent mass", also why and where we use it?

And this talk about this term in classical and quantum.

I upload paper related to this topic and there is more but I couldn't understand them.

Hello, I have some trouble understanding the position-dependent mass concept in classical mechanics especially with the lagrangian equation and the relation with the harmonic oscillator. Is there a person can provide a brief on the subject?.

I am sorry, my English is weak. Thank you for advice.

I am Libyan student, and I am studying Msc of Physics at Eastern Mediterranean University at North Cyprus. Thank you to my acceptance.
