Expansion by regions: revealing potential and Glauber regions automatically

Understand

When performing asymptotic expansions using the strategy of expansion by regions, it is a non-trivial task to find the relevant regions.

• The recently published Mathematica code asy.m automates this task, but it has not been able to detect potential regions in threshold expansions or Glauber regions.
• In this work we present an algorithm and its implementation in the update asy2.m which also reveals potential and Glauber regions automatically.
