对于真实的或p进幂幺代数群G,给定a T ∈ Hom(G,G)和T-可分解测度 如果G是“满的”或对称的,我们就得到一个分解 ,其中μ 0是T不变的, 这种分解对于移位是唯一的。我们还证明了ν 0在一些附加的充分条件下是T-可分解的,并给出了一个反例来证明这一点.我们将上述推广到p进Banach空间上的幂有界算子。我们还证明了一些收敛的类型定理p-adic群以及Banach空间。
For a real orp-adic unipotent algebraic groupG, given aT∈ Hom(G,G) andT-decomposable measure onGwhich is either ‘full’ or symmetric, we get a decomposition , where μ0isT-invariant and , and this decomposition is unique upto a shift. We also show that ν0isT-decomposable under some additional sufficient condition and give a counter example to justify this. We generalise the above to power bounded operators onp-adic Banach spaces. We also prove some convergence-of-types theorems onp-adic groups as well as Banach spaces.
