Abstract:
Quantum field theory provides a rich source of interesting and intricate divergent series and understanding their resurgence properties is both physically useful and mathematically interesting. In some cases, we also have good combinatorial control over these series as they can be viewed as generating series for suitable classes of tubings of rooted trees giving a playground where tools from all these directions can be brought to bear.
