Cauchy integral. A Cauchy integral is a definite integral of a continuous function of one real variable. Let be a continuous function on an interval and let , , . The limit is called the definite integral in Cauchy's sense of over and is denoted by The Cauchy integral is a particular case of the Riemann integral.

In this paper, we prove a common fixed point theorem for a pair of weakly compatible mappings. The result is applied to prove the existence of solution of system of nonlinear integral equations. Our theorems extend and improve several known results.

ential equations, or shortly ODE, when only one variable appears (as in equations (1.1)-(1.6)) or partial diﬀerential equations, shortly PDE, (as in (1.7)). From the point of view of the number of functions involved we may have one function, in which case the equation is called simple, or we may have several We remark that Equation (3.7) is a partial differential equation with four dependent variables: ! and the three components of V. If the velocity were known a priori, the system would be closed and we could solve Equation (3.7) for the evolution of !. Problems in which the velocity field is fixed, or specified in a advance, are call kinematic.
