Evaluating the Climate Change Model with a Mathematical Approach Involving the Cesaro Summation

Abstract

AbstractThere are numerous changes occurring daily with respect to climate. There are various factors affecting the climate. Mathematical models are framed and studied to evaluate climate change and also trying harder to curb the climate change in an optimistic way. Mathematical approaches are protracted to numerous applications in real-life circumstances. With this global pandemic, there are certainly positive and negative impacts on climate as well as human beings (Arhin-Tenkorang and Conceição in Providing global public goods: managing globalization. Oxford University Press, Oxford, 2003 [1]). Pandemic has left a mark on all the biotic and abiotic factors where we can directly or indirectly state that changes in climate affect the respiratory system most, and also, the impacts on COVID do leave a strong impact on ruining the lungs (Hogan et al. in The potential impact of the COVID-19 epidemic on HIV, TB and malaria in low- and middle-income countries. Imperial College London, 2020 [2]). “Lipot Fejer” was a Hungarian Mathematician who gave us Fejer kernel which is used to express the effect of Cesaro summation on Fourier series. The process of understanding these two concepts goes on and still is motivating and productive area of research. Cesaro summation is very forward-thinking technique to analyze diverse problems concerning sequence and series. It is related in trigonometric series and Lebesque–Riemann intervals.KeywordsClimate changeCesaro summationFejer kernel modelFourier seriesPandemicCOVID-19
