Legendre Transform Dual Asymptotic Solution for Insurers Under the Heston Local-Stochastic Volatility Model: A Comparison of Variance Premium and Expected Value Principles
This study examines optimal investment and reinsurance strategies for two competing insurers who are concerned with their relative performance. Each insurer can purchase reinsurance and invest in a financial market consisting of one risk-free asset and one risky asset, with the risky asset’s price…

b-Filter Grade of an Ideal a for Triangulated Categories
Let a and b be two homogeneous ideals in a graded-commutative Noetherian ring R, and let X be an object in a compactly generated R-linear triangulated category T. We introduce the notion of the b-filter grade of a on X, denoted by f-gradb,a,X, and provide several characterizations and bounds for…

The Proof of the Structure Stability of the Polynomial Curve Fitting Model When the Time Variable t Takes Equidistant Values
The polynomial curve fitting models are among the most common trend extrapolation prediction models. The time-independent variable t=t1,t2,⋯,tnT can take on various values during model construction, and it is a theoretical question whether different value selections will affect the model’s…

A Multistrategy Improved Archimedes Optimization Algorithm for Solving Engineering Problems
Given the shortcomings of the Archimedes optimization algorithm (AOA), the traditional AOA exhibits the following limitations: the initialization phase employs a uniform 0-1 random number distribution to generate sequences, resulting in limited diversity of initial solutions. The original density…

Composable Conditions for Constructing Knowledge Structure Based on Variable Precision FT-Rough Set Model
Constructing a knowledge structure using the variable precision FT-rough set model is an effective approach. Because directly constructing a knowledge structure for a subject or field is challenging, synthesizing global information from local information is a viable solution. However, local…

Novel Aggregation Operations of Q-Neutrosophic Hypersoft Sets and Their Applications in Sustainable Tourism Development and Cultural Preservation
When making decisions using multiple criteria, known as “multicriteria decision-making” (MCDM), it is essential to organize and address these challenges effectively. The Q-Neutrosophic Hypersoft Set (Q-NHSS) expands upon the Q-Neutrosophic Soft Set (Q-NSS) and integrates it with the Q-Fuzzy set, a…

The Effects of Fluctuating Carrying Capacity on the Dynamics of a Holling-Type III Predator–Prey Model
This study investigates the complex dynamics of a predator–prey system governed by the classical Lotka–Volterra model incorporating a Holling-type III. To capture environmental variability, the prey’s carrying capacity is modeled as a periodic function, introducing a time-dependent forcing into the…
