庞加莱(又译“彭加勒”)是19世纪末20世纪初继高斯和柯西之后,国际数学界公认的三大领袖数学家之一(其他二人为克莱因和希尔伯特)。一位数学史家评价庞加莱时说,他是“对于数学和它的应用具有全面知识的最后一人。”20世纪以来,数学进入了多学科、高难度的现代阶段,要想达到每个领域的最高成就已经不可能,但庞加莱确实是他那个时代的数学全才。 Poincaré (also translated as “Pengaler”) was one of the three leading mathematicians recognized by the international mathematics community following Goss and Cosy in the late 19th and early 20th centuries (the other two were Klein and Hilbert. ). A math historian commented Poincaré when he said that he was the last person to have complete knowledge of mathematics and its applications." Since the 20th century, mathematics has entered a multi-disciplinary, difficult modern stage, in order to reach each The highest achievements in the fields have been impossible, but Poincaré is indeed the mathematical talent of his era.
