关于光滑非负矩阵值函数的因子分解及值在多面体上的光滑函数

On factorizations of smooth nonnegative matrix-values functions and on smooth functions with values in polyhedra

N. V. Krylov

摘要:

讨论了将光滑非负矩阵值函数表示为具有正实系数且平方根为Lipschitz连续的固定矩阵的有限个线性组合的可能性。这个问题被简化为一个类似的问题,光滑函数的值在一个多面体。

英文摘要:

We discuss the possibility to represent smooth nonnegative matrix-valued functions as finite linear combinations of fixed matrices with positive real-valued coefficients whose square roots are Lipschitz continuous. This issue is reduced to a similar problem for smooth functions with values in a polyhedron.
