Distributions as Derivatives of Functionsnction space is known. As we are going to learn in the second part the dual of a Hilbert space is easily determined. Thus we use the freedom to define the topology on the test function space through various equivalent systems of norms so that we can use the simple duality theory for Hilbert spaces.

Applications of Convolution sections is a ., i.e., a relation of the form.here ., . are given distributions and . is a distribution which we want to find, in a suitable space of distributions. We will learn that various problems in mathematics can be written as convolution equations. As simple examples the case of ordinary an

Inner Product Spaces and Hilbert Spacesd of ‘Hilbert spaces’. Recall that a Euclidean space is a finite dimensional real or complex vector space equipped with an inner product (also called a scalar product). In the theory of Euclidean space we have the important concepts of the length of a vector, of orthogonality between two vectors, of

Geometry of Hilbert Spaces. This inner product provides additional structure, mainly of geometric nature. This short chapter looks at basic and mostly elementary consequences of the presence of an inner product in a (pre-) Hilbert space.

Separable Hilbert Spacess in many applications, in mathematics as well as in physics. This subclass is characterized by the property that the Hilbert space has a countable basis defined in a way suitable for Hilbert spaces. Such a ‘Hilbert space basis’ plays the same role as a coordinate system in a finite dimensional vect
