Combinatorics and physics Combinatorics and physics Combinatorial physics or physical combinatorics is the area of interaction between physics and combinatorics. "Combinatorial Physics is an emerging area which unites combinatorial and discrete mathematical techniques applied to theoretical physics, especially Quantum Theory.". "Physical combinatorics might be defined naively as combinatorics guided by ideas or insights from physics". Combinatorics has always played an important role in quantum field theory and statistical physics. However, combinatorial physics only emerged as a specific field after a seminal work by Alain Connes and Dirk Kreimer, showing that the renormalization of Feynman diagrams can be described by a Hopf algebra.

Minimum Wage in Germany a suitable minimum wage amount. The first minimum wage adjustment was made in June 2016, and was followed two years later by another adjustment, in June 2018, that rose the minimum wage to 9.19€. The minimum wage was one of the most controversial topics during the 2013 legislative election campaign. While the social democratic party - SPD, the green party - die Grünen and the left-wing party - die Linke, were in favor of a general minimum wage, the liberal party – FDP, and the conservative party – CDU, remained skeptical Leading economic research institutions, such as the CESifo Group
