In mathematics , a C 0 -semigroup , also known as a strongly continuous one-parameter semigroup , is a generalization of the exponential function. Just as exponential functions provide solutions of scalar linear constant coefficient ordinary differential equations , strongly continuous semigroups provide solutions of linear constant coefficient ordinary differential equations in Banach spaces. Such differential equations in Banach spaces arise from e. Thus, strictly speaking, a strongly continuous semigroup is not a semigroup, but rather a continuous representation of a very particular semigroup. The infinitesimal generator A of a strongly continuous semigroup T is defined by.

From the reviews: "Since E. Hille and K. Yoshida established the characterization of generators of C0 semigroups in the s, semigroups of linear operators and its neighboring areas have developed into a beautiful abstract theory. Moreover, the fact that mathematically this abstract theory has many direct and important applications in partial differential equations enhances its importance as a necessary discipline in both functional analysis and differential equations. In my opinion Pazy has done an outstanding job in presenting both the abstract theory and basic applications in a clear and interesting manner.

## Partial Differential Equations and Semigroups of Bounded Linear Operators

During the last years, several notions have been introduced for describing the dynamical behavior of linear operators on infinite-dimensional spaces, such as hypercyclicity, chaos in the sense of Devaney, chaos in the sense of Li-Yorke, subchaos, mixing and weakly mixing properties, and frequent hypercyclicity, among others. These notions have been extended, as far as possible, to the setting of C 0 -semigroups of linear and continuous operators. We will review some of these notions and we will discuss basic properties of the dynamics of C 0 -semigroups. We will also study in detail the dynamics of the translation C 0 -semigroup on weighted spaces of integrable functions and of continuous functions vanishing at infinity. Using the comparison lemma, these results can be transferred to the solution C 0 -semigroups of some partial differential equations.

Это был Хейл, примчавшийся на звук пейджера. Сьюзан услышала стук беретты, выпавшей из руки Стратмора. На мгновение она словно приросла к месту, не зная, куда бежать и что делать. Интуиция подсказывала ей спасаться бегством, но у нее не было пароля от двери лифта. Сердце говорило ей, что она должна помочь Стратмору, но .

*Ей стало плохо, когда она представила себе подобное развитие событий. Танкадо передает ключ победителю аукциона, и получившая его компания вскрывает Цифровую крепость. Затем она, наверное, вмонтирует алгоритм в защищенный чип, и через пять лет все компьютеры будут выпускаться с предустановленным чипом Цифровой крепости.*
