A selection and a fixed point theorem and an equilibrium point of an abstract economy

International Journal of Mathematics and Mathematical Sciences, 1995
A selection theorem and a fixed point theorem are proved. The fixed point theorem is then applied to prove the existence of an equilibrium point of an abstract economy.

Spin‐State Manipulation of Atomic Manganese Center by Phosphide‐Support Interactions for Enhanced Oxygen Reduction

Advanced Materials, EarlyView.
The electronic configuration of Mn single‐atom sites is regulated from low‐spin to high‐spin states by embedding well‐defined molybdenum phosphide nanocrystals nearby (MoP@MnSAC‐NC). The electronic phosphide‐support interaction between MoP and Mn single atoms drives the electronic structure transition in Mn sites from low‐spin to high‐spin states, and ...

Fixed Point Theorem for Uncommuting Mappings

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017
   In this paper we prove a theorem about the existence and uniqueness common fixed point for two uncommenting self-mappings which defined on orbitally complete G-metric space. Where we use a general contraction condition.

A fixed point theorem for non-negative functions

AIMS Mathematics
In this paper, we are concerned with the study of the existence and uniqueness of fixed points for the class of functions $ f: C\to C $ satisfying the inequality$ \ell\left(\alpha f(t)+(1-\alpha)f(s)\right)\leq \sigma \ell(\alpha t+(1-\alpha)s) $for

Enabling Additively Manufactured Electronics Through Laser Induced Graphene and Copper Deposition on Fully‐Aromatic Polyimides

Advanced Materials Technologies, EarlyView.
This article introduces a hybrid manufacturing approach to create conductive pathways in additively manufactured fully‐aromatic polyimides. This is enabled through a combination of high‐resolution laser scribing process for fabricating graphene and metallizing it with electrodeposition of copper to further increase conductivity.
