Hey 👋 Do you know best relays to be sure to miss nothing ?

Hello guys, What #relay should I join to be as much informed as possible ?

Let’s G be a set and • : G x G -> G an application (named *composition law*). A *#group * is a pair (G,•) such that : i) It exists e such that : For all x in G, x•e = e•x = x (neutral element) ii) For all x in G, it exists y in G such that : x•y = y•x = e. We denoted y by x^{-1}, x inverse. (Inverse) iii) For all x, y, z in G (x•y)•z = x•(y•z). This property is called associativity. #algebra #GaloisTheorie #Group #mathematics #maths #mathematic #math #mathforbitcoin #algebraicgeometry
