Catastrophe Theory in Explaining Price Dynamics on the Real Estate Market

Abstract The real estate market is a transparent market, which means that it is able to exchange signals with other open networks and dynamic networks. Mathematically, the evolution of a market system over time can be described mathematically. In this research, an effort was made to develop a mathematical model for visualizing the evolution of the real estate market's evolutionary path in the form of continual transitions interrupted by discontinuous changes. With the use of the catastrophe model, the qualitative evolution of the framework will be investigated.

Experience in using the methods of catastrophe theory in describing the dynamics of phytoplankton in the Vistula lagoon of the Baltic Sea

The simplest possible model of the disaster theory u2212 cusp catastrophe is used in this paper. The investigation of phytoplankton in the Russian part of the Vistula Lagoon of the Baltic Sea is carried out in this book. The quantitative parameters are used to determine the hydro-physical and hydro-chemical regimes, as well as the amount of biogenic loading on the lagoon's aquatic ecosystem are all determined. A estimation of the control parameters values is carried out using the factor loadings of the key elements for the study.

Research on the sustainability of emergency supply chain based on evolutionary game and catastrophe theory

Since the parameter combination is found in the set sum, the system is susceptible to mutation phenomenon; u2461Before the supply chain state changes abruptly, the sales chain's cooperation has grown, and member cooperation has been enhanced;.

Research on Safety Risk Management of a Steel Bracing System Based on Catastrophe Theory

Second, the safety risk was standardised, and a risk assessment instrument was developed, and a safety risk assessment index system was established; the accuracy and stability of the index system were then confirmed. Next, a disaster theory-based assessment tool was established to determine the risk level of the steel bracing device's safety risks. Finally, a steel bracing risk management process was developed, and a safety risk response was recommended based on the evaluation findings. The result was that the membership function value fell to the general risk area, which corresponds to the actual state of steel bracing in engineering, and that subsequent safety risk response steps could be carried out. The proposed method aids in determining the risk of sudden changes in steel bracing techniques, while still providing risk and response measures to ensure the steel bracing system's stability is maintained.

Earthquake Catastrophe Bond Pricing Using Extreme Value Theory: A Mini-Review Approach

While studies on EVTu2019s use in ECBPMs are still rare, EVTu2019s use in ECBPMs is still rare. Five papers were found about the use of EVT in ECBPMs, according to the selection results. Moreover, the research revealed the following: First, the generalized extreme value could remove extreme data in a period. Second, the trigger model based on two parameters is faster than one, according to the report, but it does not discuss the joint distribution of the two parameters.
