The third homology of stem-extensions and Whitehead's quadratic functor

Behrooz Mirzaii, Fatemeh Yeganeh Mokari, David M. Carbajal Ordinola

Let $A ↣ G ↠ Q$ be a stem-extension and let $ρ : A \times G \to G$ be the multiplication map. We show that there is a natural map $φ: H_1(Σ_2^ε, {\rm Tor…

Third homology of perfect central extensions

Behrooz Mirzaii, Fatemeh Yeganeh Mokari, David M. Carbajal Ordinola

For a central perfect extension of groups $A ↣ G ↠ Q$ , first we study the natural image of $H_{3} (A, Z)$ in $H_{3} (G, Z)$ . As a particula…
