    dct:description """
              $\\Phi $ be a Drinfeld $\\mathbf{F}_{q}[T]$-module of rank $2$, over a finite field $L$. Let $P_{\\Phi }(X)=$ $X^{2}-cX+\\mu P^{m}$ ($c$ an element of $\\mathbf{F}_{q}[T],$ $\\mu $ be a non-vanishing element of $% \\mathbf{F}_{q}$, $m$ the degree of the extension $L$ over the field $% \\mathbf{F}_{q}[T]/P,$ and $P$ the $\\mathbf{F}_{q}[T]$-characteristic of $% L $ and $d $ the degree of the polynomial $P$) the characteristic polynomial of the Frobenius $F$ of $L$. We will be interested in the structure of finite $\\mathbf{F}_{q}[T]$-module $L^{\\Phi }$ induced by $\\Phi $ over $L$. Our main result is analogue to that of Deuring ( see \\cite{Deuring} ) for elliptic curves : Let $M=\\frac{\\mathbf{F}_{q}[T]}{I_{1}}\\oplus \\frac{\\mathbf{F}_{q}[T]}{% I_{2}}$, where $I_{1}=(i_{1})$,$\\ \\ I_{2}=(i_{2})$\\ ( $i_{1}$, $i_{2}$ being two polynomials of $\\mathbf{F}_{q}[T]$) such that : $i_{2}\\mid (c-2)$. Then there exists an ordinary Drinfeld $\\mathbf{F}_{q}[T]$-module $\\Phi $ over $L$ of rank $2$ such that : $L^{\\Phi }$ $\\simeq M$. To cite this article: Mohamed-Saadbouh Mohamed-Ahmed , C. R.
