Bhupesh Aneja,Kanchan Sharma,Amita Rana other hand, from the physics side, too often combinatorics is viewed as a kind of uninteresting messy detail. However, there is actually a lot of beautiful and useful combinatorics in quantum field theory, and the discrete structures illuminate the physical structure. Neither side is necessarily we

We still want to have combinatorial control over the answer and so the first step is to rewrite the analytic Dyson-Schwinger equation so as to unwind the analytic side from the

Advances in Systematic Creativityexpansions but we want functions. What can we hope to do? First we can ask about asymptotics for the coefficients of our expansions. Another thing we can do is to think again about how the expansion is indexed and use that to break it up in a different way.
