,Hopf Algebra Theory of?Renormalization, physical motivation for renormalization is that the predictions from quantum field theory contain unspecified “bare” parameters, such as coupling constants, and that one needs to systematically infer these values from a measurement in order to make concrete physical predictions.

,Hopf Algebra Theory of?Renormalization,ion is entirely natural and compatible with the more traditional approach. We start in Sect.?. with a review of formal power series and Hopf algebras. While well-known to mathematicians, these topics are not usually taught in physics courses, and the section includes basic definitions and examples i

Reflections on Gender Issues in Contemporary Europeen’s movements, for the very term ‘feminism’ has been the source of considerable debate and many women, particularly in Central and Eastern Europe, remain uncomfortable with it, sometimes overtly hostile to its employment.
