CURVE FITTING – LEAST SQUARES APPROXIMATION Data
... Data analysis and curve fitting: Imagine that we are studying a physical system involving two quantities: x and y. Also suppose that we expect a linear relationship between these two quantities, that is, we expect y = ax + b, for some constants a and b. We wish to conduct an experiment to determine ...

From topological vector spaces to topological abelian groups V
... If G∧ separates the points of G, we will say that G is a DS-group. (Peter Weyl, Theorem, 1927) Compact groups are DS-groups LCA groups are DS-groups Real continuous characters have also been studied. In the class of LCA groups, groups with enough real characters are well known. They were first chara ...

Notes on logic, sets and complex numbers
... 1) Equality between sets: Two sets A and B are equal if and only if they have exactly the same elements. A = B ⇐⇒ for any x ( x ∈ A ↔ x ∈ B). 2) Subsets and Proper subsets: We say that A is a subset of B and we write A ⊆ B or B ⊇ A if every element of A is also an element of B. We say that A is a pr ...
