Webevery extension of a fully Hilbertian (or Hilbertian) ﬁeld is Hilbertian. For example, a separably closed ﬁeld is not Hilbertian, and hence not fully Hilbertian. The most general result for Hilbertian ﬁelds is Haran’s diamond theorem [10]. We prove an analog of the diamond theorem, and all other permanence criteria for fully Hilbertian ... David Hilbert was a German mathematician, one of the most influential mathematicians of the 19th and early 20th centuries. Hilbert discovered and developed a broad range of fundamental ideas in many areas, including invariant theory, the calculus of variations, commutative algebra, algebraic number theory, the foundations of geometry, spectral theory of operators and its application to i…

WebMar 13, 2024 · We study the method for response variables taking values in a general Hilbert space and for local linear smoother. We show that the procedure always improves the bias of the local linear estimator regardless of the choice of parametric model. We also illustrate the method via a real data example where the response variable is a random density.

WebNov 22, 2024 · We develop versions of the Granger–Johansen representation theorems for I (1) and I (2) vector autoregressive processes that apply to processes taking values in an arbitrary complex separable Hilbert space. This more general setting is of central relevance for statistical applications involving functional time series. WebIn addition, the method was compared with the inversion formulated in the classical Hilbertian space (i.e., X ⊆ L 2, Y ⊆ L 2). By comparing the errors achieved with the proposed variable exponent space method, it can be observed that the latter approach allows an accuracy improvement both in the investigation domain and in the target under ...
