摘要: We derive integrable equations starting from autonomous mappings with a general form inspired by the multiplicative systems associated affine Weyl group E8(1). Five such are obtained, three of which turn out to be linearisable and remaining two in terms elliptic functions. In case mappings, we non-autonomous forms contain free function independent variable present linearisation each case. The deautonomised new discrete Painleve equations. show that these fact special much richer groups E7(1) E8(1), respectively.
