Rings and Fields from Semigroups
Volker Thürey
We introduce a ring and a field, generated by a semigroup, and we investigate some of their properties.
The Cauchy-Schwarz Inequality in Complex Normed Spaces
Volker Wilhelm Thürey
We introduce a product in all complex normed vector spaces, which generalizes the inner product of complex inner product spaces. Naturally the question occurs whether the Cauchy-Sc…
The Complex Angle in Normed Spaces
Volker W. Thürey
We consider a generalized angle in complex normed vector spaces. Its definition corresponds to the definition of the well known Euclidean angle in real inner product spaces. Not su…
Hölder Functionals and Quotients
Volker W. Thürey
We describe an inequality of finite or infinite sequences of real numbers and their quotients. More precisely, we compare the quotient of Hölder functionals of two sequences of num…
Angles and a Classification of Normed Spaces
Volker Wilhelm Thürey
We suggest a concept of generalized `angles' in arbitrary real normed vector spaces. We give for each real number a definition of an `angle' by means of the shape of the unit ball.…
A Boundary Operator for Simplices
Volker W. Thürey
We generalize the very well known boundary operator of the ordinary singular homology theory, defined in many books about algebraic topology. We describe a variant of this ordinary…
