我们表明，有家庭的多项式具有小深度的算术电路，不能表示的代数分支程序的宽度为2。这阐明了计算一系列二乘二矩阵的乘积的问题的复杂性，该问题在多种设置中出现。
We show that there are families of polynomials having small depth-two arithmetic circuits that cannot be expressed by algebraic branching programs of width two. This clarifies the complexity of the problem of computing the product of a sequence of two-by-two matrices, which arises in several settings.
