我们考虑非球形巨引力子的平面波极限。我们计算坐标函数的泊松括号并找到非线性代数。我们证明这个代数解决了矩阵模型的超对称条件。这是球膜的代数实现推广为“模糊球体”。我们描述与模糊环相对应的代数的有限维表示。
We consider the plane wave limit of the nonspherical giant gravitons. We compute the Poisson brackets of the coordinate functions and find a nonlinear algebra. We show that this algebra solves the supersymmetry conditions of the matrix model. This is the generalization of the algebraic realization of the spherical membrane as the ``fuzzy sphere''. We describe finite dimensional representations of the algebra corresponding to the fuzzy torus.
