The Einstein field equations EFE; also known as “Einstein’s equations” are a set of ten partial differential equations in Albert Einstein ‘s general theory of relativity which describe the fundamental interaction of gravitation as a result of spacetime being curved by matter and energy. Not only are their solutions often unclear, but whether solutions are unique or exist at all are also notable subjects of interest.

These seemingly distinct physical phenomena can be formalised similarly in terms of PDEs. My presentations Profile Feedback Log out. In biology and economicsdifferential equations are used to model the behavior of complex systems.

Even the fundamental questions of existence, uniqueness, and extendability of solutions for nonlinear differential equations, and well-posedness of initial and boundary value problems for nonlinear PDEs are hard problems and their resolution in special cases is considered to be a significant advance in the mathematical theory cf.

This means that the ball’s acceleration, which is a derivative of its velocity, depends on the velocity and the velocity depends on time.

Views Read Edit View history. We think you have liked this presentation. The solution may not be unique. An equation containing only first derivatives is a first-order differential equationan equation containing the second derivative is a second-order differential equationand so on.

A differential equation is a mathematical equation that relates some function with its derivatives. The mathematical theory of differential equations first developed together with the sciences where the equations had originated and where the results found application.


Just as ordinary differential equations often model one-dimensional dynamical systemspartial differential equations often model multidimensional systems. Inspection Separation of variables Method of undetermined coefficients Variation of parameters Integrating factor Integral transforms Euler method Finite difference method Crank—Nicolson method Runge—Kutta methods Finite element method Finite volume method Galerkin method Perturbation theory.

Differential equations first came into existence with the invention of calculus by Newton and Leibniz. There are very few methods of solving nonlinear differential equations exactly; those that are known typically depend on the equation having particular symmetries.

He solves these examples and others using infinite series and discusses the non-uniqueness of solutions. Nonstiff problemsBerlin, New York: In pure mathematicsdifferential equations are studied from several different perspectives, mostly concerned with their solutions—the set of functions that satisfy the equation.

Linear differential equations are the differential equations that are linear in the unknown function and its derivatives. A First Course in Differential Equations 5th ed.

The rate law or rate equation for a chemical reaction is a differential equation that links the reaction rate with concentrations or pressures of reactants and constant parameters normally rate coefficients diferencisles partial reaction orders.

What is essential is that we can determine as many coefficients as we want. Bouce equations can be divided into several types. These fields in turn underlie modern electrical and communications technologies.

In some cases, this differential equation called an equation of motion diprija be solved explicitly. For first order initial value problems, the Peano existence theorem gives one set of circumstances in which a solution exists.

Auth with social network: All of these disciplines are concerned with the properties of differential equations of various types. Their difeenciales is well developed, and, in many cases, one may express their solutions in terms of integrals.

Nonhomogeneous 2 nd Order D. Not to be confused with Difference equation.

Historically, the problem of a vibrating string such as that of a musical instrument was studied by Jean le Rond d’AlembertLeonhard EulerDaniel Bernoulliand Joseph-Louis Lagrange. See Ordinary differential equation for other results. Archived from the original PDF on The theory of differential equations is closely related to the theory of difference equationsin which the coordinates assume only discrete values, and the relationship involves values of the unknown function or functions and values at nearby coordinates.


Retrieved from ” https: PDEs can be used to describe a wide variety of phenomena in nature such as soundheatelectrostaticselectrodynamicsfluid flowelasticityor quantum mechanics. All of them may be described by the same second-order partial differential equationthe wave equationwhich allows us to think of light and sound as forms of waves, much like familiar waves in the water.

The Lotka—Volterra equationsalso known as the predator—prey equations, are a pair of first-order, non-lineardifferential equations frequently used to describe the population dynamics of two species that interact, one as a predator and the other as prey. Both further developed Lagrange’s method and applied it to mechanicswhich led to the formulation of Lagrangian mechanics.

Instead, solutions can be approximated using numerical methods. For example, the harmonic oscillator equation is an approximation to the nonlinear pendulum equation that is valid for small amplitude oscillations see below.

Thus x is often called the independent variable of the equation. Byoce ordinary differential equation ODE is an equation containing an unknown function of one real or complex variable xits derivatives, and some ecyaciones functions of x.
