We study infinite words coding an orbit under an exchange of three intervals which have full complexity C(n) = 2n + 1 for all n ∈ N (non-degenerate 3iet words). In terms of parameters of the interval exchange and the starting point of the orbit we characterize those 3iet words which are invariant under a primitive substitution. Thus, we generalize the result recently obtained for sturmian words.
We study hyperbolic systems of one-dimensional partial differential equations under general, possibly non-local boundary conditions. A large class evolution equations, either on individual 1-dimensional intervals or general networks, can be reformulated in our rather flexible formalism, which generalizes the classical technique first-order reduction. forward and backward well-posedness; further...
let a be a bounded linear operator on a banach space x. we investigate the conditions of existing rank-one operator b such that i+f(a)b is invertible for every analytic function f on sigma(a). also we compare the invariant subspaces of f(a)b and b. this work is motivated by an operator method on the banach space ell^2 for solving some pdes which is extended to general operator space under some ...
background: invariant natural killer cells (inkt) are an important immunoregulatory t cell subset. currently several flow cytometry-based approaches exist for the identifi-cation of inkt cells, which rely on using the 6b11 monoclonal antibody or a combina-tion of anti-vα24 and anti-vβ11 antibodies. objective: the aim of this study was to compare the ability of two flow cytometry-based methods f...
