Let Mi be the set of all sequences {a.);, of real num bers such that Σ converges. More formally, we could write this as 1 lal M1a :(W) ai R and i=1 We introduce a function p: Mi x MiR by setting 95 Let (Mi,p) denote the particular metric space we introduced above, and for each X = {xīた1 e M and for each i, we refer to the number xi as the ith coordinate of X. For each N...
Let be such that Prove that thenAE Mmxn AT A= I n. m> n AE Mmxn AT A= I n. m> n
a) Prove algebraically that(m+n | p+n)≥(m | p) for all m, p, n ∈
N and such that m≥p.
b) Prove the above inequality by providing a combinatorial
proof. Hint: this can be done by creating a story to count the RHS
exactly (and explain why that count is correct), and then providing
justification as to why the LHS counts a larger number of
options.
a) Prove algebraically that p for all m, p, n EN, and such that m...
