On singularity confinement for the pentagram map [PDF]
The pentagram map, introduced by R. Schwartz, is a birational map on the configuration space of polygons in the projective plane. We study the singularities of the iterates of the pentagram map.

Singularity confinement as an integrability criterion [PDF]
Abstract In this paper we present a rigorous method for deciding whether a birational three point mapping that has the singularity confinement property is integrable or not, based only on the structure of its (confined) singularity patterns.

Bridging the chiral symmetry and confinement with singularity
We consider a holographic quark model where the confinement is a consequence of the quark condensate. Surprisingly, the equation of motion of our holographic model can be mapped to the old spin-less bag model.

Full-deautonomisation of a class of second-order mappings in ancillary form [PDF]
We present an application of the full-deautonomisation method to a class of secondorder mappings which, using an ancillary variable, can be cast into a form that greatly facilitates the study of their singularities.

SIGMA-MESON AND CONFINEMENT SINGULARITY [PDF]
) into twopoles which are diving on the second sheet of the complex-s plane. Thepoles correspond to states which are mixtures of gluonic, flavour-singlet qq¯,and ππ components. The low-lying pole is located at the complex-M region(690 ± 160) − i(400 ± 150) MeV, the second one goes in the region of largemasses: (ReM >∼ 1400, −ImM >∼ 500) MeV.

Singularity Confinement and Chaos in Discrete Systems [PDF]
We present a number of second order maps, which pass the singularity confinement test commonly used to identify integrable discrete systems, but which nevertheless are non-integrable. As a more sensitive integrability test, we propose the analysis of the complexity (``algebraic entropy'') of the map using the growth of the degree of its iterates ...

Point singularity array with metasurfaces [PDF]
Phase singularities are loci of darkness surrounded by monochromatic light in a scalar field, with applications in optical trapping, super-resolution imaging, and structured light-matter interactions.

Singularity confinement in delay-differential Painlevé equations
Abstract We study singularity confinement phenomena in examples of delay-differential Painlevé equations, which involve shifts and derivatives with respect to a single independent variable. We propose a geometric interpretation of our results in terms of mappings between jet spaces, defining certain singularities analogous to those of ...

Singularity confinement and algebraic entropy: the case of the discrete Painlevé equations [PDF]
We examine the validity of the results obtained with the singularity confinement integrability criterion in the case of discrete Painlevé equations. The method used is based on the requirement of non-exponential growth of the homogeneous degree of the iterate of the mapping.
