| A Banach space is a real or complex normed vector space that is complete as a metric space under the metric induced by the norm. |
|
| His mathematical publications started in 1964 with a series of papers on topological algebras, measure algebras and Banach algebras. |
|
| A Banach space is a vector space with a norm, but not necessarily given by an inner product. |
|
| Normed and Banach spaces, linear functionals, the dual of a Banach space, weak convergence and linear operators. |
|
| Many of Riesz's fundamental findings in functional analysis were incorporated with those of Stefan Banach of Poland. |
|
| Kalecki was the third Pole to be honoured in this way by OUP, which has also published the complete works of Nicolaus Copernicus and Stefan Banach. |
|
| Already in these cases there is convergence in Banach spaces that are not only infinite-dimensional but nonseparable. |
|
| Stefan Banach, one of the most influential mathematicians of the 20th century, one of the principal founders of modern functional analysis. |
|
| These were the notions of a Hilbert space and a Banach space, named after the German mathematician David Hilbert and the Polish mathematician Stefan Banach, respectively. |
|
| Banach extended Hilbert's ideas considerably. |
|
| Our aim in this paper is to present results of existence of fixed points for continuous operators in Banach spaces using measure of noncompactness under an integral condition. |
