Industrial Policy for Southern Europe, star-triangle uniqueness relations are methods for evaluating massless diagrams. The method of IR rearrangement , also in a generalized version based on the ..-operation , is a method oriented at renormalization-group calculations.浓缩 发表于 2025-3-22 09:39:29
Book 2005 variety of methods for evaluating Feynman integrals has been developed over a span of more than fifty years, this book is a first attempt to summarize them. .Evaluating Feynman Integrals. characterizes the most powerful methods, in particular those used for recent, quite sophisticated calculations,难理解 发表于 2025-3-22 15:49:42
IBP and Reduction to Master Integrals,er integrals. In contrast to the evaluation of the master integrals, which is performed, at a sufficiently high level of complexity, in a Laurent expansion in ɛ, the reduction problem is solved at ., and the expansion in ɛ does not provide simplifications here.难理解 发表于 2025-3-22 20:18:54
Evaluation by Differential Equations,tegrals. Thus, this basic method is oriented at the evaluation of the master integrals. Moreover, in contrast to other methods of evaluating individual Feynman integrals, it is assumed within this method that a solution of the reduction problem is already known.Harass 发表于 2025-3-23 00:39:51
