درسنا في هذا البحث قابليّة حلّ معادلة بل في مجموعة الأعداد الصّحيحة ، حيث أعطينا شرطاً لازما و كافياً لقابليّة حلّ هذه المعادلة بالإعتماد على الإيديالات في مرتّبات الحقول التّربيعيّة الحقيقيّة، كما أعطينا صيغة الإيديال المقابل لكلّ حلّ لهذه المعادلة و ذلك من أجل حالات خاصّة .
In this paper , we will study the ability to solve Pell's equation in the
set Z, we give necessary and sufficient conditions to solve this equation , depending on the
ideals in orders of the real quadratic fields .We also introduce the formula of the opposite
ideal for every solution of this equation , in special cases.

In this paper, we introduce an algorithm to solve the
Advection equation by finite element method. In this method, we
have chosen Three pattern of cubic B-Spline to approximate the
nonlinear solution to convert the nonlinear PDE into a system of
In this work, we studied Pell equations X2 - DY2 = ±2. We showed when both
of these equations are solvable, and we found the necessary and sufficient
condition for the solubility of each one by the continued fractions and the
concept of the central norm.
In this paper , we will define multiple orthogonal vector of Diophantine
equation on specific conditions. We will solve the Diophantine equation
with this vector in ternary number system and develop special
