Loop algebra and visaoro symmetries of integrable hierarchies of KP type
(2001-01-01)
We propose a systematic treatment of symmetries of KP integrable systems, including constrained (reduced) KP models cKP R, M (generalized AKNS hierarchies), and their multi component (matrix) generalizations. Any cKP R, M ...
Affine Lie algebraic origin of constrained KP hierarchies
(1995-12-01)
An affine sl(n + 1) algebraic construction of the basic constrained KP hierarchy is presented. This hierarchy is analyzed using two approaches, namely linear matrix eigenvalue problem on hermitian symmetric space and ...

Constrained KP models as integrable matrix hierarchies
(1997-03-01)
We formulate the constrained KP hierarchy (denoted by cKP K+1,M) as an affine sl(M + K+ 1) matrix integrable hierarchy generalizing the Drinfeld-Sokolov hierarchy. Using an algebraic approach, including the graded structure ...

Solitons from dressing in an algebraic approach to the constrained KP hierarchy
(Iop Publishing Ltd, 1998-11-27)
The algebraic matrix hierarchy approach based on affine Lie sl(n) algebras leads to a variety of 1 + 1 soliton equations. By varying the rank of the underlying sl(n) algebra as well as its gradation in the affine setting, ...

Characterisation and performance of three Kenaf coagulation products under different operating conditions
(2021-01-01)
The Sustainable Development Goal (SDG) 6.1, established by the United Nations General Assembly in 2015, targets universal and equitable access to safe and affordable drinking water for all by 2030. An essential factor in ...
