A fixed-point theorem of Krasnoselskii

Applied Mathematics Letters, 1998
Abstract Krasnoselskii's fixed-point theorem asks for a convex set M and a mapping Pz = Bz + Az such that: 1. (i) Bx + Ay ∈ M for each x , y ∈ M 2. (ii) A is continuous and compact 3. (iii) B is a contraction. Then P has a fixed point.

Some ergodic theorems over $k$-full numbers [PDF]

arXiv
In 2022, Bergelson and Richter established a new dynamical generalization of the prime number theorem. Later, Loyd showed a disjoint form with the Erd\H{o}s-Kac theorem. Recently, the author and his coauthors proved some ergodic theorems over squarefree numbers related to these results.

Minimax and fixed point theorems

Mathematische Annalen, 1980
Since then, numerous applications of this interesting theorem have been found. The object of this note is to obtain a generalization of Theorem 1 by relaxing, among the others, the compactness condition. It contains a fixed point theorem for maps with inwardness or outwardness conditions given by Fan [6]. As its direct consequence, we also obtain a new

A Survey on Universal Approximation Theorems [PDF]

arXiv
This paper discusses various theorems on the approximation capabilities of neural networks (NNs), which are known as universal approximation theorems (UATs). The paper gives a systematic overview of UATs starting from the preliminary results on function approximation, such as Taylor's theorem, Fourier's theorem, Weierstrass approximation theorem ...
