Let M n be the semigroup of n × n complex matrices under the usual multiplication, and let S be different subgroups or semigroups in M n including the (special) unitary group, (special) general linear group, the semigroups of matrices with bounded ranks. Suppose Λ k (A) is the rank-k numerical range

Let M n be the algebra of all n × n complex matrices. For 1 ~< k ~< n, the kth numerical range of A 6 M, is defined by Wk(A) = {(i/k)E~=,x\*~Axj: {x t ..... x k} is an orthonormal set in C"}. It is known that {tr A/n} = W,(A) ~ W n\_ 1(A) c\_ ... c\_ WI(A). We study the condition on A under which W~
We investigate explicit higher order time discretizations of linear second order hyperbolic problems. We study the even order (2m) schemes obtained by the modified equation method. We show that the corresponding CFL upper bound for the time step remains bounded when the order of the scheme increases
