For the generalized DS equations, we showed that the KMV symmetry algebra can be present only if the conditions ( 21 ), under which the symmetry algebra is isomorphic to that of
In the previous section we showed that the Christoffel transformation of Hermite’s elliptic LBP gives polynomials orthogonal on the unit circle with explicit reflection
But the effective theory ( 3.3 ) shows a second order transition from the symmetric to a antiferromagnetic phase and we can compare critical exponents at this transition with those
In the simplest case of r = 2 we write down the Poisson structures on this space and on the spaces of representatives for the BV system (Propositions 2 and 4 ) and compare them
In higher dimensions, the usual highest weight representations apply for the symmetry algebra of the Laplace–Beltrami operator. In this case there is no longer a single chain
The boundary tridiagonal algebra reveals algebraic properties of the asymmetric open exclusion process which are deeply related to the Askey–Wilson polynomials and allow for the
The article discusses how the self-adjoint domains can be identified in terms of a boundary condition for the asymptotic behaviour of the wave functions around the singularity, and
the present application to phantom energy one might try to use the above mechanism to generate standard symmetry break by starting with a graded Lie algebra but using all vector
