Edmond Nicolas Laguerre was a brilliant French mathematician. He was born in Bar-le-Duc, France, on April 9, 1834. He passed away in the same town on August 14, 1886. Laguerre became a member of the important Académie des sciences (French Academy of Sciences) in 1885.
His main work focused on two big areas of math: geometry and complex analysis. Geometry is about shapes, sizes, positions, and properties of space. Complex analysis deals with special numbers called complex numbers.
He also studied something called orthogonal polynomials. These are special types of mathematical expressions that are very useful in many areas of science and engineering. The ones he studied are now known as Laguerre polynomials.
Laguerre also developed a way to find the roots (solutions) of mathematical equations called Laguerre's method. This method is especially helpful for polynomials. He also created new ideas in geometry, including the Laguerre plane and the Laguerre transformation.
His Work
Edmond Laguerre wrote several important mathematical books and articles. These works helped to shape how mathematicians understood geometry and other advanced topics.
Key Publications
- He wrote a book called Théorie des équations numériques (Theory of Numerical Equations) in 1884. This book explored how to solve equations using numbers.
- His collected works, Oeuvres de Laguerre, were published after his death. Important mathematicians like Charles Hermite and Henri Poincaré helped put them together.
