"In the years immediately following the invention of the laser, its potential for application to the study of a broad class of physical and chemical problems was perceived by many people. However, the use of early lasers in these studies was severely constrained by the limited number of available wavelengths. In 1966 P. P. Sorokin and, independently, F. P. Schafer, demonstrated that stimulated ...

Standing (solitary)-wave/steady-state solutions in many nonlinear wave motions and Schrodinger flows lead to nonlinear eigenproblems. In [X. Yao and J. Zhou, SIAM J. Sci. Comput., 29 (2007), pp. 1355-1374], a Rayleigh-local minimax method is developed to solve iso-homogeneous eigenproblems. In this subsequent paper, a unified method in Banach spaces is developed for solving non iso-homogeneous ...

In response to comments by Borovoi [J. Opt. Soc. Am. A 19, 2517 (2002)] on my earlier work [J. Opt. Soc. Am. A 18, 1929 (2001)], the kinetic approach to extinction is compared with the traditional radiative transfer formalism and advantages of the former are illustrated with concrete examples. It is pointed out that the basic differential equation dI(l) 5 2csI(l)dl already implies perfect rando...

We show that all supersymmetric Type IIA D-branes can be constructed as bound states of a certain number of unstable non-supersymmetric Type IIA D9-branes. This string-theoretical construction demonstrates that D-brane charges in Type IIA theory on spacetime manifold X are classified by the higher K-theory group K(X), as suggested recently by Witten. In particular, the system of N D0-branes can...
