I'm trying to implement this loss function : MCFD_loss_function from this document (P6) : Loss functions So I created a new function like this : def mcfd_loss(y_true, y_pred): return K.sum( # ∑ K.cast( K.greater( # only…

How to calculate the set of algebraic integers in $\mathbb{Z}[\zeta_n]$ for any positive integer n, where $\zeta_n$ is the n’th root of unity. I will be very happy if someone give me the answer. Thanks in advance. I tried using basis….but I am…

I'd like to do exact computations on regular polygons. To do so, I wrote the code you find below. But the expression cos*cos will not compile. Apparently multiplication is not defined for the algebraic number type I'm using. I guess I'll have to try…

I want to calculate the cohomology of the sheaf Q in the exact sequence on $\mathbb P^3$: 0\rightarrow\mathcal O(-1)\rightarrow \mathcal O^{\oplus 4}\rightarrow Q\rightarrow 0 To do it, I want to calculate the cohomology of Q, using Macaulay2. I…
