1-Generic Degrees Bounding Minimal Degrees Revisited
We show that over the base system P− + Σ2-bounding, the existence of a 1-generic degree < 0′′ bounding a minimal degree is equivalent to Σ2-induction.

متن کاملOn quantum field theories with finitely many degrees of freedom
The existence of inequivalent representations in quantum field theory with finitely many degrees of freedom is shown. Their properties are exemplified and analysed for concrete and simple models. In particular the relations to Bogoliubov–Valatin quasi-particles, to thermo field dynamics, and to q–deformed quantum theories are put foreward. The thermal properties of the non-trivial vacuum are gi...
متن کاملGeneric critical points of normal matrix ensembles
The evolution of the degenerate complex curve associated with the ensemble at a generic critical point is related to the finite time singularities of Laplacian Growth. It is shown that the scaling behavior at a critical point of singular geometry x ∼ y is described by the first Painlevé transcendent. The regularization of the curve resulting from discretization is discussed. PACS numbers: 05.30...
متن کاملDeconfined quantum critical points.
The theory of second-order phase transitions is one of the foundations of modern statistical mechanics and condensed-matter theory. A central concept is the observable order parameter, whose nonzero average value characterizes one or more phases. At large distances and long times, fluctuations of the order parameter(s) are described by a continuum field theory, and these dominate the physics ne...
