摘要:

本文将定义在紧群上的向量测度和连续函数的傅里叶-斯蒂尔切斯变换推广到局部紧群上。为此,我们考虑一个局部紧群G的正规紧子群K的一个表示L,并且我们使用由L的表示导出的G的一个表示。然后,从G的表示出发,定义了G上向量测度和具有紧支集的连续函数的傅里叶-斯蒂尔切斯变换.然后,利用G的一个正规紧子群的酉表示诱导G的表示,将紧群的Shur正交关系推广到局部紧群.这种扩展使我们能够开发一个傅里叶-斯蒂尔切斯变换的系列形式,是线性的,连续的,可逆的。

英文摘要:

In this work we extend the Fourier-Stieltjes transform of a vector measure and a continuous function defined on compact groups to locally compact groups. To do so, we consider a representation L of a normal compact subgroup K of a locally compact group G, and we use a representation of G induced by that of L. Then, we define the Fourier-Stieltjes transform of a vector measure and that of a continuous function with compact support defined on G from the representation of G. Then, we extend the Shur orthogonality relation established for compact groups to locally compact groups by using the representations of G induced by the unitary representations of one of its normal compact subgroups. This extension enables us to develop a Fourier-Stieltjes transform in series form that is linear, continuous, and invertible.
