The construction of 7-membered ring via direct C7–H cyclization of benzoimidazoles with alkenes would provide a more atom- and step-economical route to tricyclic imidazoles and derivatives that widely exist in a broad range of bioactive molecules.

In this paper, we present modified modulus-based synchronous multisplitting iteration methods based on multisplittings of the system matrix for solving the large sparse linear complementarity problems. The proposed methods extend the existing modulus

On generalized eigenvalue perturbation bounds for diagonalizable matrix pairs upper bounds are discussed all the time. In this paper we mainly consider not only upper bounds but also lower bounds of perturbation of generalized eigenvalues for diagona

In this paper we present the analytic solutions of the following constrained matrix determinant and trace minimization and maximization problems: $\min_{U_{1},\ldots, U_{m}\in\mathbb{U}_{n}}\vert\d...

The coupled Gross–Pitaevskii system studied in this paper is an important mathematical model describing spin-1 Bose-Einstein condensate. We propose a linearized and decoupled compact finite difference scheme for the coupled Gross–Pitaevskii syste

In this paper we provide the explicit expression and sharper bounds of the chordal metric between generalized singular values of Grassmann matrix pairs. The new results involve the constrained opti...

As we know, the exoplanets are mostly detected by the methods of radial velocity and transit, up to now only one is found by the astrometric method. As the data of the gaia will be soon released, astrometry will gradually become one of the most impor

In this paper we consider new perturbation bounds analysis of a kind of generalized saddle point systems. We provide perturbation upper bounds for the solutions of generalized saddle point systems, which extend the corresponding results in [W.-W. Xu,
