Riesz basis problem help

show all work please

Consider the space V = Span({o(t - n) }nez), where 1/4 $ (t ) = Is {o(t - n) }nez a Riesz basis for V and if so, what are the constants A, B? (You should be able to compute these to a high degree of accuracy.) You might find the following fact useful in your analysis: 1/4 $(jn) = ete int dt = (21)1/4e-12/4. - DODefinition. We say {un} is a Riesz basis if there exists constants A, B > 0 such that 2 A Clan|2 5 an Un
