Sigma-Algebra, Measures, Properties of Measures
Let m be a sigma-algebra, M_1 and M_2 are measures on m. a). Is M = M_1 + M_2 a measure? b). Is M = M_1 - M_2 a measure? c). Is M = M_1M_2 a measure? Either prove or disprove by providing a counter example.
Prove that the following function is Borel-measurable function. f_n(t) = { [t*2^n]*2^-n , 0 < t < n, n , t > or = to n | f_n(t) - t | < 2^-n , t < n } I want a detailed proof. I want to kn ...continues

Real Analysis (Elementary sets)
1). Let M be an elementary set. Prove that | closure(M)M | = 0. ( closure of M can also be written as M bar, and it is the union of M and limit points of M). 2). If M and N are elementary sets then show that | M union N | + | M intersection N| = |M| + |N| The def of elementary set : If M is a union of finite members of d ...continues

Borel measurable (Borel functions)
1).Let f(X) : R -> R be the following: f(x) = { 1 if x is in Q (rationals) , 0 if x is not in Q ( irrational)} Prove that f(x) is Borel measurable ( Borel functions).
Borel measurable (Borel functions)
Let f(x) be { 1/x if x is not 0. and 1 if x = 0} . Prove that f(x) is borel function ( borel measurable).
