B_{p q}^{r + 1}

is not defined to be the image of

d_{p_{1} q_{1}}

. Rather, it is the preimage of

Find the fourier transform of

f (t) = e^{- a t}

https://math.stackexchange.com/questions/1147876/find-the-fourier-transform-of-ft-e-at

You're correct that

lim_{t \to \infty} e^{i t}

doesn't exist. But

∥ e^{i t} ∥ \leq 1

for all values of

t

lim_{t \to \infty} e^{- t} = 0

, it follows that

lim_{t \to \infty} e^{- (1 - i) t} = lim_{t \to \infty} \to 0 e^{- t} \cdot bounded e^{i t} = 0 .
