Quadratic-growth tau-sequence conjecture for octagon posets
Octagon-poset tau-sequence conjecture. For each octagon poset , the -system associated with admits a strong -sequence consisting of irreducible Laurent polynomia…

Eigenvalue read-off conjecture for deautonomised confining mappings
Eigenvalue read-off conjecture. If the deautonomisation is sufficiently general, then the value of the largest eigenvalue of the linear map on the Picard group, and hence the algeb…

Picard-action conjecture for confining plane mappings
Picard-action conjecture. For any confining mapping of the plane, the behaviour of the parameters satisfying the confinement constraints is governed by the linear action on the Pic…

Irreducibility and co-primeness conjecture for discrete mappings
The source discusses irreducibility and co-primeness of iterated terms for discrete mappings, and relates these properties to singularity structure and integrability. In particular…

General correspondence between singularity confinement and exceptional-curve dynamics
Consider a non-autonomous mapping regularised by blowing up its indeterminacy points, and the induced map on the exceptional curves. The singularity-confinement conditions are obta…

Similarity of parameter and Picard-group matrices under deautonomisation
Let and be the non-negative integers specifying the blow-up patterns, and let the matrix governing the evolution of the mapping's parameters be compared with the mat…

Co-primeness as a criterion for singularity confinement and integrability
A nonlinear partial difference equation is said to have singularity confinement when its singularities do not propagate indefinitely, and two terms are co-prime when they share no…

Singularity confinement conjecture for the pentagram map in even dimension
Singularity confinement conjecture. Singularity confinement holds generically on unless
