 Report summary:
 We introduce the notion of crossed module for pre-Lie–Rinehart algebras and prove that they are classified by the third cohomology of pre-Lie–Rinehart algebras. We also introduce the notion of pre-Lie-Rinehart 2-algebras and show that there is a one-to-one correspondence between strict pre-Lie-Rinehart 2-algebras and crossed modules for pre-Lie Rinehart algebras.
