Japanese: 放物型方程式 - ほうぶつがたほうていしき(英語表記)parabolic equation
Parabolic equation - HOBUTSUGATAHOTEISHIKI (English spelling) parabolic equation
The basic form of a parabolic equation, which is a type of partial differential equation, is written as ∂u / ∂tc⊿uf ( t , x )……(1) ( t >0,⊿= ∂2 /∂x12 ……+ ∂2 / ∂xn2 ). Here, c is a positive constant and f is a known function. In physics, this equation describes the heat conduction or diffusion phenomenon of a substance, and the unknown function u =u ( t , x ) represents the temperature or concentration of the diffusing substance at time t and the point in space x =( x1 ,…… , xn ) . Usually, the problem is to find a solution to equation (1 ) that satisfies the initial condition, u (0, x )= u0 ( x )…… ( 2).
