18 окт. 2017 г. · By definition, any Borel measure acts on the Borel σ-algebra, so only sets in that σ-algebra are Borel measurable. Thus, a set being Borel ... |
14 февр. 2021 г. · The definition of a Borel measurable function is that the preimages of Borel sets are Borel. R is a very Borelly Borel set, so f−1(R)=B is Borel as well. |
22 сент. 2020 г. · Every Borel measurable set is Lebesgue measurable since B∈B(R), then B is a Lebesgue measurable set except perhaps on a set of measure 0. |
20 апр. 2015 г. · A Borel measurable function is always Lebesgue measurable since any Borel set is Lebesgue measurable. The converse is not true. |
3 нояб. 2015 г. · For real functions a measurable function usually means that the preimage of any borel set is a measurable set (ie in the Lebesgue σ-algebra) ... |
18 мая 2017 г. · A Borel measurable function is a measurable function but with the specification that the measurable space X is a Borel measurable space. |
10 февр. 2021 г. · But it is easy to see that the sets {x∈Rn:|f(x+h)−f(x)−Th|≤ϵ‖h‖} are Borel measurable sets. So, since all intersections and unions in (1) are ... |

27 мар. 2014 г. · Each analytic set(for example, f(B) in my example) is universally measurable. Hence, it is μ-measurable. Theorem 2.2.13 asserts that an ... |
15 мая 2020 г. · It is known that whenever f:R→R is Borel measurable it is not necessarily true that f(X) is Borel measurable for Borel X. |
