Thousands of particles of light can merge into a type of 'super photon' under suitable conditions. Physicists call such a state a photon Bose-Einstein condensate. Researchers have now shown that this ...

SIAM Journal on Applied Mathematics, Vol. 31, No. 2 (Sep., 1976), pp. 379-384 (6 pages) Given a real n × n matrix M and vector q, the linear complementarity problem is to find vectors w and z such ...

We prove the following statements about bounded linear operators on a separable, complex Hilbert space: (1) Every normal operator $N$ that is similar to a Hilbert ...
