In 1992 Greither [10] refined the method of Rubin and used the Euler system of cyclotomic units to give an elementary (but technical) proof of the second version of the Main
We give a new proof of the K-theoretic analogue of the Kirwan surjectivity theorem in symplectic geometry (see Harada–Landweber, 2007) by using the equivariant version of the Kirwan
Using the previous results of the author on the existence of elliptic Riemann–Hilbert problems for generalized Cauchy–Riemann systems, we indicate some classes of systems which
Using this representation theorem and the deterministic characterizations of exponential stability and uniform observability obtained in [ 16 ], [ 17 ], we will prove a result of
In the first section of this paper, we give some assumptions and prelimi- naries, in section 2 and section 3, we prove the existence of an absorbing set and the existence of
In the present study, using the characterizations of measures of noncompactness we prove a theorem on the existence and local asymptotic stability of solutions for a
We prove necessary and sufficient conditions for Ψ − (uniform) stability of the trivial solution of a nonlinear Lyapunov matrix differential equation. But the obtained results in
We first establish the global stability of the trivial and nontrivial constant steady states for the reaction diffusion system, and then prove the existence and non-existence
