Multiple Normalized Solutions for Nonlinear Biharmonic Schr?dinger Equations in ■with L-Subcritical Growth

引用

Acta Mathematicae Applicatae Sinica 2024年

作者： Jun WANG Li WANG ji-xiu WANG Department of Mathematics Sun Yat-sen University College of Science East China Jiaotong University School of Mathematics and Statistics Hubei University of Arts and Science

In this article, we consider the existence of normalized solutions for the following nonlinear biharmonic Schr?dinger equations:■where c, ε > 0, N ≥ 5, λ ∈ R is a Lagrange multiplier and is unknown, h ∈ C（■N, [0, ∞）), f : R → R is continuous function satisfying L2-subcritical growth. When ε is small enough, we get multiple normalized solutions. Moreover, we also obtain orbital stability of the solutions.

Information Protocol Equilibrium in n-insider Perfect Competition with a Random Deadline

引用

Acta Mathematicae Applicatae Sinica 2024年

作者： Qi-hong NIE ji-xiu QIU ji-ze LI Yong-hui ZHOU School of Big Data and Computer Sciences Guizhou Normal University School of Mathematical Sciences Guizhou Normal University

This paper studies a model of n insiders with perfect information trading on a risky asset with value normally distributed and disclosed at a random deadline. We propose a concept of information protocol equilibrium under semi-strong efficient pricing, consisting of an n-profile of insider trading strategies with terminal residual information protocols, and find that if a common protocol on terminal residual information before trading is obeyed by all insiders, then, in the market with more than two insiders there exists a uique equilibrium only when it requires to release common partial information eventually, or it does not exist if it requires to release all or not any; but in the market with a single insider, the insider may release all private information eventually to make a maximal profit. Thereby, the existence and uniqueness of information protocol equilibrium among n insiders are deduced. Finally, numerical results illustrate some market characteristics of equilibria with different information protocols required before trading.
