The extended discrete gradient method is an extension of traditional discrete gradient method,which is specially designed to solve oscillatory Hamiltonian s
While the theory of orthogonal polynomials is rich and fairly comprehen-sive,very little is known about polynomials orthogonal with respect to a complex-val
Due to the rapid development in experimental technology such as laser cool-ing and atom and molecule trapping etc.,the spectra of many light atoms and molec
The modern physics education in China has started at around the beginning of the 20th century.Over the years the physics knowledge has been spread out into
This talk is concerned with the group structure of extend Runge–Kutta– Nystr(o)m(ERKN)methods.We first establish the ERKN group Ω and the RKN group G for
The Vlasov{Maxwell equation is a di?erential equation describing time evolu-tion of the distribution function of plasma consisting of charged particles with
The current talk concerns the uniform and high-order discretization of the novel geometric integration approach to the computation of Sturm-Liouville proble
