An irreducibly simple climate-sensitivity model is designed to empower even non-specialists to research the question how much global warming we may cause. In 1990, the First Assessment Report of the Inter- governmenta...
The notions of mixed monotone decomposition of dynamical systems are introduced. The fundamental idea is to make an elaborate use of the natural growth and decay mechanism inherent in the structure of a dynamical syst...
Ⅰ. INTRODUCTIONWhittaker first studied the relation between the first integral and integral invariant, and proved that an integral invariant can be determined by a given first integral. Recently, Mei Fengxiang furthe...
A kind of important complex dynamical behaviour of dynamical systems is the sensitivity of the primary value perturbation for the systems, i. e. under the primary value perturbation, the larger change of the asymptoti...
There is a profound and essential relation between the conservative quantity of dynamical systems and the inherent dynamics symmetry. The well-known Noether

It is well-known that partial stability is an active modern problem. About stationary linear systems, a lot of results on partial stability have been obtained. For time-varying linear systems, however, the general the...

Ⅰ. INTRODUCTION AND RESULT Let H be a Hilbert space with its inner product (· , ·) and norm ‖·‖. Let etA be a C0-semigroup on H with the infinitesimal generator A and
In society, there extensively exist hierarchical control structures such as corporation (?) factory (?) workshop (?) working-set. These structures as realia form an organic whole with the basic subsystems (for example...
