Abstract and figures This work presents the development of a two-species prey and predator model in the context of global warming. Studies indicate prey’s growth rate and predator anxiety are inversely correlated. Furthermore, evidence supports as global warming increases, prey’s carrying capacity may decline. Predators are thought to be able to work together to pursue prey. Furthermore, current thinking holds that the direction of the wind may affect how much prey the predator consumes. Scholars propose that when global warming increases, predator growth rates may decline. Additionally, experts argue that the intraspecies competition among predators, which is reliant on the density of the current prey, may result in a decline in the number of predators. It is widely accepted that the rate of global warming is constant. Furthermore, the prevailing view is that both predator and prey species may be involved in the rise in global warming. It is commonly understood that several industrial and ecological measures could reduce global warming. The model’s solution’s positivity and boundedness have been examined. Various equilibrium points are assessed, and the system’s stability is examined around these places. The Hopf bifurcation around the positive equilibrium point is investigated. Via numerical simulation and testing on a virtual data set, all theoretical results are experimentally validated.

The purpose of this work is to guarantee that solutions to the first order multiple delay differential equation (FOMDDE) exist that are constrained by new sufficient conditions. The existence of the solution with bounded properties by monotonic functions is successfully demonstrated by these requirements. We used an example to demonstrate the power of novel conditions.

In this work, we use Krasnoselskii’s Theorem to prove an existence for the solutionsfor delay differentials equation under new sufficient conditions and bounded by decreasingfunctions.:

This paper addresses the existence of bounded solutions for second-order nonlinear delay differential equations. It presents new sufficient conditions to demonstrate that the solutions are bounded by decreasing functions. Additionally, an example is provided to validate the applicability of these conditions

AbstractIn this paper, some conditions to guarantee the existence of bounded solution tothe second order multi delayed arguments differential equation are given. TheKrasnoselskii theorem used to the Lebesgue’s dominated convergence and fixed pointto obtain some new sufficient conditions for existence of solutions. Some importantlemmas are established that are useful to prove the main results for oscillatoryproperty. We also submitted some sufficient conditions to ensure the oscillationcriteria of bounded solutions to the same equation (PDF) Existence and Qualitative Property of Differential Equation with Delayed Arguments.

This study investigated a novel cryptographic approach involving the encryption ofplaintext using the coefficients of a Taylor series for the logarithm function multiplied by itscorresponding index. The decryption process utilized the Laplace transform of the logarithmfunction and its inverse. Through this methodology, several innovative mathematicalencryptions and decryption formulas were derived. The study also includes a practicalexample to demonstrate the broader implications of the findings (PDF) © A new approach of cryptography using taylor series of logarithm function.
