We investigate the spectral properties of Schrdinger operators with point interactions, focusing attention on the interplay between level repulsion (von Neumann-Wigner theorem) and the symmetry of the confi.guration of point interactions. The explicit solution of the problem allows observing level ...
We investigate the spectral properties of Schrodinger operators with point interactions, focusing attention oil the interplay between level repulsion (von Neumann-Wigner theorem) and the symmetry of the configuration of point, interactions.

约翰·冯·诺依曼(John von Neumann,1903~1957)于1903 年 12 月 28 日生于布达佩斯银行家家庭,逝于 1957 年 2 月 8 日,享年 54 岁。原籍匈牙利,布达佩斯大学数学博士。他是 20 世纪最重要的数学家之一,在现代计算机、博弈论、核武器和生化武器等领域内的科学全才之一,被后人称为“计算机之父”和“博弈论之...
The noncrossing rule for potential energy surfaces can be applied only, as originally postulated by von Neumann and Wigner, to slowly occurring changes; it has, however, over many years, been widely used to rationalize fast chemical reactions. Taking the conversion of Dewar benzene to benzene as...
The school had another outstanding mathematician one year ahead of von Neumann, namely Eugene Wigner. World War I had relatively little effect on von Neumanns education but, after the war ended, Béla Kun controlled Hungary for five months in 1919 with a Communist government. The Neumann family...

Von Neumann was regarded as an extraordinary phenomenon even by the cleverest people in the world. The Nobel-winning physicist and mathematician Wigner said of von Neumann: ‘I have known a great many intelligent people in my life. I knew Planck, von Laue and Heisenberg. Paul Dirac was my ...
