Countability Properties of Weakly Compact Sets in Asymmetric Locally Convex Spaces
Jobst Ziebell
A dual pair formulation for asymmetric locally convex spaces is developed that strictly generalises the ordinary vector space setting. The concept of a polar topology carries over…
Wetterich's Equation and its Boundary Conditions for Radon Measures on Locally Convex Spaces
Jobst Ziebell
Wetterich's equation and corresponding flows of effective average actions are used frequently in theoretical physics to study the properties of quantum field theories. Under approp…
Tikhonov Well-Posedness and Differentiability on Asymmetrically Normed Spaces
Jan Fischer, Jobst Ziebell
On normed vector spaces there is a well-known connection between the Tikhonov well-posedness of a minimisation problem and the differentiability of an associated convex conjugate f…
Existence theorem on the UV limit of Wilsonian RG flows of Feynman measures
Andras Laszlo, Zsigmond Tarcsay, Jobst Ziebell
In nonperturbative formulation of Euclidean signature quantum field theory (QFT), the vacuum state is characterized by the Wilsonian renormalization group (RG) flow of Feynman meas…
Existence and Construction of Exact FRG Flows of a UV-Interacting Scalar Field Theory
Jobst Ziebell
We prove the existence and give a construction procedure of Euclidean-invariant exact solutions to the Wetterich equation in dimensions satisfying the naive boundary condit…
FlexibleSUSY: Precise automated calculations in any BSM theory
Peter Athron, Markus Bach, Dylan Harries +7
FlexibleSUSY is a software package for various calculations in any model of physics beyond the standard model (not just any supersymmetric model). FlexibleSUSY can solve boundary v…
