the advance of dynamics concept started with the paintings of Isaac Newton. In his conception the main easy legislations of classical mechanics is f = ma, which describes the movement n in IR. of some extent of mass m lower than the motion of a strength f via giving the acceleration a. If n the location of the purpose is taken to be some extent x E IR. , and if the strength f is meant to be a functionality of x purely, Newton's legislations is an outline when it comes to a second-order usual differential equation: J2x m dt = f(x). 2 It is sensible to lessen the equations to first order via defining the velo urban as an additional n autonomous variable by way of v = :i; = ~~ E IR. . Then x = v, mv = f(x). L. Euler, J. L. Lagrange and others studied mechanics through an analytical procedure known as analytical dynamics. at any time when the strength f is represented through a gradient vector box f = - lU of the capability strength U, and denotes the adaptation of the kinetic strength and the capability power by means of 1 L(x,v) = 2'm(v,v) - U(x), the Newton equation of movement is decreased to the Euler-Lagrange equation ~~ are used because the variables, the Euler-Lagrange equation could be If the momenta y written as . 8L y= 8x' extra, W. R.

Marek Kuczma used to be born in 1935 in Katowice, Poland, and died there in 1991. After completing highschool in his domestic city, he studied on the Jagiellonian collage in Kraków. He defended his doctoral dissertation less than the supervision of Stanislaw Golab. within the 12 months of his habilitation, in 1963, he received a place on the Katowice department of the Jagiellonian collage (now collage of Silesia, Katowice), and labored there until eventually his dying.
