Research Article Nonlinear Mean Ergodic Theorems for Semigroups inHilbert Spaces
Let K be a nonempty subset of a Hilbert space , where K is not necessarily closed and convex. A family Γ= {T(t); t ≥ 0} of mappings T(t) is called a semigroup on K if (S1) T(t) is a mapping from K into itself for t ≥ 0, (S2) T(0)x = x and T(t+ s)x = T(t)T(s)x for x ∈ K and t,s≥ 0, (S3) for each x ∈ K , T(·)x is strongly measurable and bounded on every bounded subinterval of [0,∞). Let Γ be a se...
متن کاملMean Ergodic Theorems for C0 Semigroups of Continuous Linear Operators
In this paper we obtained mean ergodic theorems for semigroups of bounded linear or continuous affine linear operators on a Banach space under non-power bounded conditions. We then apply them to the wave equation and the system of elasticity to show that the mean of their solutions converges to their equilibriums.
متن کاملErgodic Theorems
Every one of the important strong limit theorems that we have seen thus far – the strong law of large numbers, the martingale convergence theorem, and the ergodic theorem – has relied in a crucial way on a maximal inequality. This is no accident: it can in fact be shown that a maximal inequality is a necessary condition for an almost everywhere convergence theorem. We will refrain from carrying...
متن کاملAnalogs of Wiener’s Ergodic Theorems for Semisimple Lie Groups, Ii
X f dm, provided the action is ergodic. The main tool used in the proof of this result is Wiener’s maximal inequality, which asserts that the maximal function f ∗ β (x)= supt>0 |π(βt )f (x)| satisfies m{x : f ∗ β (x)≥ δ} ≤ (C/δ)‖f ‖L1(X). Consider the following generalization of the foregoing setup. LetG be a connected Lie group G, and let K be a compact subgroup. Assume there exists a G-invari...
متن کاملErgodic Theorems in Demography
The ergodic theorems of demography describe the properties of a product of certain nonnegative matrices, in the limit as the number of matrix factors in the product becomes large. This paper reviews these theorems and, where possible, their empirical usefulness. The strong ergodic theorem of demography assumes fixed age-specific birth and death rates. An approach to a stable age structure and t...
