Symmetry Groups of Hypergeometric Series
Structures of symmetries of transformations for Holman-Biedenharn-Louck
hypergeometric series: terminating balanced series and
elliptic series are discussed. Namely the description of the
invariance groups and the classification all of possible transformations for
each types of hypergeometric series are given. Among them, a "periodic"
affine Coxeter group which seems to be new in the literature arises as an
invariance group for a class of series
Variational Structures for Infinite Transition Orbits of Monotone Twist Maps
In this paper, we consider chaotic dynamics and variational structures of
area-preserving maps. There is a lot of study on the dynamics of their maps and
the works of Poincare and Birkhoff are well-known. To consider variational
structures of area-preserving maps, we define a special class of
area-preserving maps called monotone twist maps. Variational structures
determined from twist maps can be used for constructing characteristic
trajectories of twist maps. Our goal is to prove the existence of an infinite
transition orbit, which represents an oscillating orbit between fixed points
infinite times, through minimizing methods.Comment: arXiv admin note: substantial text overlap with arXiv:2212.0185
