ǫ-Finite Basis of Master Integrals for the Integration-By-Parts Method
It is shown that for every problem within dimensional regularization, using the Integration-By-Parts method, one is able to construct a set of master integrals such that each corresponding coefficient function is finite in the limit of dimension equal to four. We argue that the use of such a basis simplifies and stabilizes the numerical evaluation of the master integrals. As an example we expli...
متن کاملIntegration by Parts for Oscillatory Integrals. DRAFT
Assume we have a definite integral we wish to evaluate, but it looks nasty because the integrand is wildly oscillatory and the usual numerical techniques based on sampling will not work well. The approach we take is to reformulate the indefinite integral so it doesn’t wiggle so much. That is, we compute another form for the anti-derivative. Using the fundamental theorem of integral calculus (wh...

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
