Generalized Riemann-Hilbert-Birkhoff Decomposition and a New Class of Higher Grading Integrable Hierarchies
H. Aratyn, C. P. Constantinidis, J. F. Gomes +2
We propose a generalized Riemann-Hilbert-Birkhoff decomposition that expands the standard integrable hierarchy formalism in two fundamental ways: it allows for integer powers of La…
New negative grade solitonic sector for supersymmetric KdV and mKdV hierarchies
Y. F. Adans, A. R. Aguirre, J. F. Gomes +2
A systematic construction for supersymmetric negative graded (non-local) flows for mKdV and KdV based on with a principal gradation is proposed in this paper. We show tha…
Extended symmetry of higher Painlevé equations of even periodicity and their rational solutions
Henrik Aratyn, José Francisco Gomes, Gabriel Vieira Lobo +1
The structure of extended affine Weyl symmetry group of higher Painlevé equations of periodicity depends on whether is even or odd. We find that for even , the symmetry…
SKdV, SmKdV flows and their supersymmetric gauge-Miura transformations
Y. F. Adans, A. R. Aguirre, J. F. Gomes +2
The construction of Integrable Hierarchies in terms of zero curvature representation provides a systematic construction for a series of integrable non-linear evolution equations (f…
Two-fold degeneracy of a class of rational Painlevé V solutions
H. Aratyn, J. F. Gomes, G. V. Lobo +1
We present a construction of a class of rational solutions of the Painlevé V equation that exhibit a two-fold degeneracy, meaning that there exist two distinct solutions that shar…
