The supersymmetric model of 1] for the evolution of the genetic code is elaborated. Energy considerations in nucleic acid strand modelling, using sl(2) polarity spin and sl(2=1) family box quartet symmetry, lead for the case of codons and anticodons to assignments of codons to 64-dimensional sl(6=1) ' A(5; 0) multiplets. In a previous paper 1] we(More)
The combinatorics of the BPHZ subtraction scheme for a class of ladder graphs for the three point vertex in φ 3 theory is transcribed into certain connectivity relations for marked chord diagrams (knots with transversal intersections). The resolution of the singular crossings using the equivalence relations in these examples provides confirmation of a(More)
Rules for quantizing the walker+coin parts of a classical random walk are provided by treating them as interacting quantum systems, forming a quantum statistical model of a particle (walker) immersed in a bath of other particles (coins). Quantum walks following the so called U-and ε-quantization rules are presented. The former rule involves unitary(More)
