Cau·chy

 (kō-shē′), Baron Augustin Louis 1789-1857.
French mathematician whose Cours d'analyse (1821) introduced modern rigor into calculus. He founded the theory of functions of a complex variable and made contributions to the mathematical theory of elasticity and the wave theory of light.

Strichartz Estimates and the Cauchy Problem for the Gravity Water Waves Equations
Yellow-vest representative Benjamin Cauchy said protesters would be out on New Year's Eve as well, to show that the mobilisation will not end in the new year".
"We didn't want a suspension, we want the past increase in the tax on fuels to be canceled immediately," Benjamin Cauchy, the organizer of the Yellow Vests movement, told BFM TV.
The Cauchy problem for regular equations was investigated, e.g., in well known works [3,4,5,7,9,12], but for singularly perturbed equations it has not been considered previously.
Then, there is a study on Cauchy sequence in an NSNLS in Section 4.
The guide service identified the dead skier as Dr Emmanuel Cauchy, who notably treated French climber Elisabeth Revol after she survived a storm in the Himalayas in January that killed her Polish climbing partner.
For the local and global well-posedness of the Cauchy problem we refer to [12-14] and references cited therein.
Then in Section 3 the origin of the dual kinetic evolution is stated; namely, a low-density (Boltzmann-Grad) limit of a nonperturbative solution of the Cauchy problem of the dual BBGKY hierarchy is established.
It is sufficient to prove that the sequence {[[sigma].sub.m], ([x.sub.n], [y.sub.n])} is Cauchy in R.
We first study some properties of a regular function and then generalize Cauchy integral theorem and Cauchy integral formula in [A.sub.n](R).
Let us consider finite difference approximation of the Cauchy problems of nonlinear partial differential equations (PDE's) of the normal form, and we show here its convergence independently of stability of the Cauchy problems.
