In the mathematical study of differential equations, the Dirichlet (or first-type) boundary condition is a type of boundary condition, named after Peter Gustav Lejeune Dirichlet (1805–1859). When imposed on an ordinary or a partial differential equation, it specifies the values that a solution needs to … Meer weergeven ODE For an ordinary differential equation, for instance, PDE For a partial differential equation, for example, Meer weergeven Many other boundary conditions are possible, including the Cauchy boundary condition and the mixed boundary condition. The latter is a combination of the Dirichlet and Neumann conditions. Meer weergeven • Neumann boundary condition • Robin boundary condition • Boundary conditions in fluid dynamics Meer weergeven
