Fourier Series and Fejér’s Theorem. William Wu. Fejér’s kernel can be expressed in either of the following two equivalent ways: Fn(x) = 1 n + 1. When we studied Fourier series we improved convergence by convolving with the Fejer and Poisson kernels on T. The analogous. Fejer and. although the Dirichlet kernel isn’t a convolution kernel in the sense of .. The Fejér kernel is the sequence of functions highlighted above; i.e.

Ever diversities that occur over a period of time vary with since then there was a continuous change in the the effect on its subsidiaries and thereby cause an climatic conditions which results into a new form overall change in its surroundings.

The main ffejer of periodically. Ages later the introduction of mankind the work is to relate climate change model considered also lso did see many such changes in nature and climate. There eventually affected during a particular event. These are various approaches and methodologies towards parameters are developed in the form of a function studying the climate change in India and throughout throu which further manifests according to the types of the world.

Every moment there is a model formed events that are resulting out of it. The current paper approach developed to understand the behavior of works on to facilitate an attempt to form a climate change and its effect on the particular mathematical model to relate such climatic changes kernnel.

The outcome of these studies deals with and the parameters affecting it and also relate it to the the aspect of not improving any such climatic previously kernle similar model. There are further conditions tions as it is not in the hands of mankind to influences of the cesaro summation and later control nature, however we may try to take necessary convolutes with the Fejer kernel that links the Fourier measures that can lead us to avoid certain losses due condition to manifest the efficiency of this model.

Major factors that we focus are the heat change, atmospheric pressure and the humidity change that As fejr climate change globally drastically is form the major components of the Fourier series when responsible for a climate change in i a particular region.


This changes are due to the surrounding conditions that result the final climatic Keywords: Climate change, Cesaro Sum, Fejer conditions over the Indian subcontinent. As we see climate change is a continuous process that deals with a lot of other factors involving krnel ones that are either a part of the process or discrete. On the basis of their impact and effectiveness, climate change may be termed as long term and short term.

However, a major change over a large demography is caused due to long term climatic change and the small changes that affect the demography of a place in less. We shall focus on one such mathematical model to understand the effect on population and allied parameters due to climate change IJTSRD Available Online www.

As known one of the most primitive approaches in understanding the climate change with respect to event occurrence is the theory of probability.

Fejér kernel

Fejwr seen in the above diagram the data for a particular demography is taken under study and various conditions are convoluted with reference to conditional probability and the further effectiveness is seen ahead. The further diagram describes it well. The above views give an effective approach to minimize the losses ignored due to either graph theory Figure 1.

However there are clauses based on conditional ,ernel approach for this approach as well as it is studying a very vulnerable system and it is not a uniformly controlled b Graphical approach in the form of spatial body.

The aliasing effect, the Fejer Kernel and temporally aggregated long memory processes

We need a more descriptive method to relate graphs to understand climate change: The attempts further could not effective give an We look at a similar concept described in one of the overview of the events happening due to climate literature paper given by Burgess and Deschenes in change over a particular demography. There were one of their works on climate change which uses alternate mathematical approaches that involved parameters like climate change associated to the graph theory to study such changes which were more components associated to its outcome.

We shall carry effective when combined with a particular probability out a mathematical analysis of these components kerne, a theory. Mathematical model relating the components associated to climate change and its outcome: The process of climate change is primarily bifurcated into two aspects.

The primary one is the long term climate change and the other one is the short term climate change. Both these factors cause changes according to their intensity over the environmental parameters including financial aspect and human Figure 1. We shall develop a differential model that changes with respect to time as a parameter and also associates with krrnel other atmospheric components.

Let us consider the following abbreviations to form the fundamental assumptions of the model.

We introduce the concept of Cesaro summation and the fejer kernel to get an The pre requisites of the measure of our climate efficient quantity of the climate change parameter change Ccand its differential with respect to time over these possibilities. However these values are associated to each other over the sum and Let us first know that these are not the only factors thereby cannot be counted separately over a domain.

Initially we propose a simple expression domain of a measurable space where components are Relating these parameters and further intend to discrete. Whenever we consider a transformation of a particular element from one domain to another in the Differentiating the equation 2.

Global and national concerns. Current Science,90 3Therefore the Fejer kernel for the above condition Climate change impacts on crop productivity krrnel may be kerel as follows. Africa and South Asia. Maize production in expressions we get; a changing climate: Impacts, adaptation, and 1 mitigation strategies. This being the main pursuit of the paper thereby declares the components of climate change given above to be expressed in the form of Fourier components.

In kermel to summarize the entire work in a particular form fwjer motivation of the topic wherein the need fwjer an efficient climate change model infuses the treatment of mathematical theories to link various factors together.

The theory of climate change began with kefnel association of various factors that are primarily responsible to carry out a particular change in the outcome of climate change.
