Structure of local Banach spaces of locally convex spaces

摘要:

我们证明了连续双线性映射P:C(I)\times C(I)\to C(I)可以表示为形式P(f,g)= B((Af)(Ag)),其中A和B是C(I)上的有界线性算子,乘法定义为逐点的,当且仅当对于I中的所有t,双线性型(f,g)-> P(f,g)g)(t)是关于C(I)乘以C(I)的积分,并且在某种意义上连续地依赖于t。为此,我们构造了一个连续满射phi:I \to I^2,其中允许Pelczynski意义上的正则平均算子。

英文摘要:

We show that a continuous bilinear mapping P: C(I) \times C(I) \to C(I) can be presented in the form P(f,g) = B((Af)(Ag)), where A and B are bounded linear operators on C(I) and multiplication is defined pointwise, if and only if for all t in I the bilinear form (f,g) -> P(f,g)(t) is integral on C(I) times C(I) and depends in a sense continuously on t. To this end we construct a continuous surjection phi : I \to I^2 admitting a regular averaging operator in the sense of Pelczynski.
