Stability Analysis for Memristor-Based Complex-Valued Neural Networks with Time Delays
Entropy, 2019 In this paper, the problem of stability analysis for memristor-based complex-valued neural networks (MCVNNs) with time-varying delays is investigated extensively. This paper focuses on the exponential stability of the MCVNNs with time-varying delays.

Singular higher order boundary value problems for ordinary differential equations
Electronic Journal of Qualitative Theory of Differential Equations, 2009 We study singular boundary value problems for differential equations with left focal boundary conditions of the form, $$(-1)^{n} u^{(n)}(t) + f(t,u(t), \ldots, u^{(n-2)}(t)) = 0, \quad t \in (0,1),$$ $$u^{(n-1)}(0) = u^{(n-2)}(1) = \cdots = u(1) = 0 ...

An index for Brouwer homeomorphisms and homotopy Brouwer theory [PDF]
, 2015 We use the homotopy Brouwer theory of Handel to define a Poincar{\'e} index between two orbits for an orientation preserving fixed point free homeomorphism of the plane.

The Fuzzy Brouwer Fixed-Point Theorem
Journal of Mathematical Analysis and Applications, 1998 It is proved that the Brouwer fixed-point theorem continues to hold for Hutton's \(L\)-cubes (with finite or countably many factors) provided that \(L\) is a completely distributive lattice with a countable base. It is worthwhile to point out that in a forthcoming paper by the author and the reviewer [Fuzzy Sets Systems, 1999] it is proved that the ...

Random Carbon Tax Policy and Investment Into Emission Abatement Technologies
Mathematical Finance, EarlyView.ABSTRACT We analyze the problem of a profit‐maximizing electricity producer, subject to carbon taxes, who decides on investments into CO2$\rm CO_2$ abatement technologies. We assume that the carbon tax policy is random and that the investment in the abatement technology is divisible, irreversible, and subject to transaction costs.

Network Games With Triadic Interactions
International Economic Review, Volume 67, Issue 2, Page 605-632, May 2026.ABSTRACT We propose a model for network‐mediated interactions incorporating higher‐order relationships such as triadic interactions. The marginal utility of an individual's action depends explicitly on endogenous actions of multiple units. Conditions ensuring a unique Nash equilibrium are derived using a variational inequality approach. We estimate the

Planar bilipschitz extension from separated nets
Journal of the London Mathematical Society, Volume 113, Issue 4, April 2026.Abstract We prove that every L$L$‐bilipschitz mapping Z2→R2$\mathbb {Z}^2\rightarrow \mathbb {R}^2$ can be extended to a C(L)$C(L)$‐bilipschitz mapping R2→R2$\mathbb {R}^2\rightarrow \mathbb {R}^2$, and we provide a polynomial upper bound for C(L)$C(L)$. Moreover, we extend the result to every separated net in R2$\mathbb {R}^2$ instead of Z2$\mathbb {Z}

From Simplices to Abstract Convex Spaces: A brief history of the KKM theory [PDF]
Results in Nonlinear Analysis, 2018 We review briefly the history of the KKM theory from the original KKM theorem on simplices in 1929 to the birth of the new partial KKM spaces by the following steps.
