12 mag 2024 · Joseph Fourier, French mathematician, known also as an Egyptologist and administrator, who exerted strong influence on mathematical physics. He showed how the conduction of heat in solid bodies may be analyzed in terms of infinite mathematical series now called by his name, the Fourier series.

3 giorni fa · In mathematical analysis, the Dirac delta function (or δ distribution ), also known as the unit impulse, [1] is a generalized function on the real numbers, whose value is zero everywhere except at zero, and whose integral over the entire real line is equal to one. [2] [3] [4] Since there is no function having this property, modelling the delta ...
24 mag 2024 · This chapter is devoted to the most popular and extremely important in various applications of Fourier series and its generalizations. Joseph Fourier made in nineteen century a remarkable discovery of function's expansion defined on a prescribed finite interval into infinite series of trigonometric functions.
17 mag 2024 · Fourier series, in mathematics, an infinite series used to solve special types of differential equations. It consists of an infinite sum of sines and cosines, and because it is periodic (i.e., its values repeat over fixed intervals), it is a useful tool in analyzing periodic functions.
