AFFINE LIE ALGEBRA SYMMETRY OF SINE-GORDON THEORY AT REFLECTIONLESS POINTS [PDF]
Modern Physics Letters A, 1996 The quantum affine symmetry of the sine-Gordon theory at q2=1, which occurs at the reflectionless points, is studied. Conserved currents that correspond to the closure of simple root generators are considered, and shown to be local. We argue that they satisfy the [Formula: see text] algebra. Examples of these currents are explicitly constructed.

Lie Symmetry Analysis of a Nonlinear Black–Scholes Equation in Illiquid Markets
International Journal of Mathematics and Mathematical SciencesWe have conducted comprehensive Lie symmetry analysis of a nonlinear Black–Scholes equation that arises in illiquid markets. The equation incorporates nonlinearities arising from market constraints, such as transaction costs and liquidity effects.
