“…--HTML--><p>The Tunneling Potential Formalism offers an alternative to the Euclidean bounce formalism for computing tunneling actions, which determine the decay of metastable vacua in quantum field theory. In this discussion, I will explore how this formalism can be applied to investigate various other problems, such as bubble-of-nothing decays, ungauged Q-balls, and more.…”

“…This book, written by well-known experts in the field, offers a concise summary of one of the latest and most significant developments in the theoretical analysis of quantum field theory. The renormalization group is the name given to a technique for analyzing the qualitative behavior of a class of physical systems by iterating a map on the vector space of interactions for the class. …”

The present book is devoted to the study of topological properties of this space and of similar moduli spaces, such as the space of real algebraic curves, the space of mappings, and also superanalogs of all these spaces. …”
