Abstract<br />
The goal of the present work is to enumerate polyominoes of minimal area<br />
plus one inscribed in a rectangle by combinatorial methods. In the first chapter,<br />
1 present the definitions and classifications of polyominoes and a brief<br />
generalization of polyominoes of minimal area. Then, in chapter two 1 describe<br />
the algebra of ordinary and exponential generating functions and ,a<br />
tool that serves to explain the exact enumerative formulas for polyominoes<br />
of minimal area and minimum area plus one treated in the chapter three. In<br />
chapter three, we develop a combinatorial method for enumerating polyominoes<br />
of minimal area plus one ; their generating series, their generalization,<br />
their exact enumeration formulas and sorne applications. This chapter is a review<br />
of a document, written by my dissertation advisor, on the enumeration<br />
of inscribed polyominoes.<br />
And finally, in chapter four , 1 present the algorithm that generates the main<br />
program and polyominoes without cycles and the source code. This program<br />
was used as a database to check the exact formulas presented in this mas ter<br />
thesis.
