Single projection method for pseudo-monotone variational inequality in Hilbert spaces

Optimization, 2018
In this paper, a projection-type approximation method is introduced for solving a variational inequality problem. The proposed method involves only one projection per iteration and the underline operator is pseudo-monotone and L-Lipschitz-continuous. The

Eigendecompositions of Transfer Operators in Reproducing Kernel Hilbert Spaces

Journal of nonlinear science, 2017
Transfer operators such as the Perron–Frobenius or Koopman operator play an important role in the global analysis of complex dynamical systems. The eigenfunctions of these operators can be used to detect metastable sets, to project the dynamics onto the ...

Weak Hilbert Spaces

Proceedings of the London Mathematical Society, 1988
In a recent paper by \textit{V. D. Milman} and the author [Isr. J. Math. 54, 139-158 (1986; Zbl 0611.46022)] the notion of weak cotype 2 and weak type 2 Banach spaces were introduced. In the present paper the author considers the class of Banach spaces which are both of weak type 2 and weak cotype 2.

Embeddings of persistence diagrams into Hilbert spaces

Journal of Applied and Computational Topology, 2019
Since persistence diagrams do not admit an inner product structure, a map into a Hilbert space is needed in order to use kernel methods. It is natural to ask if such maps necessarily distort the metric on persistence diagrams.

On the Metric Distortion of Embedding Persistence Diagrams into Separable Hilbert Spaces

International Symposium on Computational Geometry, 2018
Persistence diagrams are important descriptors in Topological Data Analysis. Due to the nonlinearity of the space of persistence diagrams equipped with their {\em diagram distances}, most of the recent attempts at using persistence diagrams in machine ...

Weaving K-Frames in Hilbert Spaces

, 2017
Gǎvruta introduced K-frames for Hilbert spaces to study atomic systems with respect to a bounded linear operator. There are many differences between K-frames and standard frames, so we study weaving properties of K-frames.
