Hilbert Space...
Can somebody tell me the difference between H1 & H2 hilbert spaces?

These are two special Sobolev spaces, namelyamalmirando said:Can somebody tell me the difference between H1 & H2 hilbert spaces?
H1 and H2 Hilbert Spaces are both types of infinite-dimensional vector spaces, but they differ in their properties and functions. H1 Hilbert Spaces are used to model functions that are square-integrable, while H2 Hilbert Spaces are used for functions that are not necessarily square-integrable but can be approximated by square-integrable functions.
H1 and H2 Hilbert Spaces are essential tools in functional analysis, which is a branch of mathematics that studies infinite-dimensional vector spaces. They are used in various areas of mathematics and science, such as quantum mechanics, signal processing, and data analysis.
Yes, the function f(x) = 1/sqrt(x) belongs to H1 Hilbert Space but not H2 Hilbert Space. This is because f(x) is square-integrable, but its square is not integrable. In contrast, all functions in H2 Hilbert Space have integrable squares.
H1 and H2 Hilbert Spaces share some common properties, such as being complete, separable, and having an orthonormal basis. However, H1 Hilbert Spaces are reflexive, while H2 Hilbert Spaces are not. Additionally, H1 Hilbert Spaces have a stronger notion of convergence than H2 Hilbert Spaces.
Yes, H1 and H2 Hilbert Spaces have many real-world applications. For example, H1 Hilbert Spaces are used in digital signal processing to represent signals and in quantum mechanics to describe wave functions. H2 Hilbert Spaces are used in image and video processing to approximate images and videos and in machine learning to model complex data.
