Аннотация:
Обсуждаются и иллюстрируются на двухпетлевых примерах общие правила вычисления коэффициентов при произвольных степенях и логарифмах в асимптотическом разложении фейнмановских диаграмм в судаковском пределе. Описаны особенности, связанные с вычислением отдельных членов в разложении, в частности введение вспомогательной аналитической регуляризации.
