We construct the Darboux transformation with Dihedral reduction group for the 2–dimensional generalisation of the periodic Volterra lattice. The resulting Bäcklund transformation can be viewed as a nonevolutionary integrable differential difference equation. We also find its generalised symmetry and the Lax representation for this symmetry. Using formal diagonalisation of the Darboux matrix we ...

‎in this paper‎, ‎we obtain the dimensions of symmetry classes of polynomials associated with‎ ‎the irreducible characters of the dihedral group as a subgroup of‎ ‎the full symmetric group‎. ‎then we discuss the existence of o-basis‎ ‎of these classes‎.

This paper introduces skew dihedral group rings and their applications for public-key cryptography. We present a specific ring that is the underlying algebraic platform our cryptographic constructions. then build two-party key exchange protocol an analysis of its security. exploit it to derive agreement protocol, probabilistic scheme, encapsulation mechanism. In addition security constructions,...
