Marston Morse and his mathematical works

A Reduction of the Schoenflies Extension Problem by Marston Morse

1. In his study of the Schoenflies extension problem Mazur, [ l ] , includes the hypothesis that the given mapping be "semilinear" in a neighborhood of some point in the shell domain of <£. In Mazur's paper the problem of removing this hypothesis is unsolved. We shall show how to remove this hypothesis, leaving the "shell hypothesis." In the process of doing this we establish two fundamenta...

Leonhard Euler: His Life, the Man, and His Works

On the occasion of the 300th anniversary (on April 15, 2007) of Euler’s birth, an attempt is made to bring Euler’s genius to the attention of a broad segment of the educated public. The three stations of his life—Basel, St. Petersburg, and Berlin—are sketched and the principal works identified in more or less chronological order. To convey a flavor of his work and its impact on modern science, ...
