The aim is, step by step, to isolate $k$ on one side of the equation. By multiplying both sides with the LCD of all the fractions, we obtain an equation with no fractions: (LCD=24) $\displaystyle... | |
# Model evaluation for feature selection
I have a dataset of gene expression data and I'm trying to find genes related to particular diseases. My labels are dichotomous (sick - not sick) and I used a Logistic regression with LASSO regularization in order to extract meaningful features (basically taking all the genes w... | |
# Commutator subgroup and bijective representation
Let $G$ be a finite group and $G' = [G,G]$ be its commutator subgroup, which is defined to be the subgroup generated by elements $[g,h] = g^{-1}h^{-1}gh$ for all $g,h \in G$, where $G'$ is a normal subgroup of $G$. And $G/G'$ is abelian.
Prove that for any field $\ma... | |
# Show $\text{Gal}(K_\infty/\mathbb Q)\cong \mathbb Z_p^{\times}$
Let $\zeta_{p^n}$ be the primitive $p^n$-th root of unity where $p$ is a prime and $K_n=\mathbb Q(\zeta_{p^n})$ the $p^n$-th cyclotomic field. Let $K_\infty=\bigcup K_n$.
Could someone give a proof of the isomorphism $\text{Gal}(K_\infty/\mathbb Q)\con... | |
