comment Error bound for the truncated Fourier series of a multidimensional Lipschitz function
@user127096 You raise a good point. Let's say $N= N_1 \cdot N_2 \cdot \ldots \cdot N_n$, where $N_1$ is the number of term in the direction $i_1$.

comment Is finding the maximum of a polynomial of degree one a linear programming problem?
@MichaelC.Grant I see that my proposed equivalent is wrong. Can you indicate how to get, or if possible write as an answer, the equivalent problem using binary constraints? I tried to find my way with google, but I don't see how to do it.

@MichaelC.Grant I think, the 'max' in the problem can be 'linearized' so that the problem becomes an LP (see edit). Is it true?

comment What is the error when approximating $L^2([0,1])$ by a finite dimensional space?
@PrahladVaidyanathan Yes, thank you. I forgot to say that $X$ contains only bounded function. I added it.

@PrahladVaidyanathan I see, I miswrite the max notation. I have corrected it, is it better now?
