Description

Besides its various applications in string and D-brane physics, the $θ$-deformation of space (-time) coordinates (naively called the noncommutativity of coordinates), based on the $\star$-product, behaves as a more general framework providing more mathematical and physical informations about the associated system. Similarly to the Gelfand-Dickey framework of pseudo differential operators, the Moyal $θ$-deformation applied to physical problems makes the study more systematic. Using these facts as well as the backgrounds of Moyal momentum algebra introduced in previous works [21, 25, 26], we look for the important task of studying integrability in the $θ$-deformation framework. The main focus is on the $θ$-deformation version of the Lax representation of two principal examples: the $sl_2$ KdV$_θ$ equation and the Moyal $θ$-version of the Burgers systems. Important properties are presented.
