WebElliptic curves (over elds of characteristic p) have formal groups of height 1 or 2. We shall call a trivializable elliptic curve over a Z (p)-algebra Rordinary if the formal group Cb has height 1 (where C the base change of the curve to R=p). Let (Mord ell) Z (p) denote the moduli stack of ordinary elliptic curves, and de ne (Mord ell) Z (p) WebCommutative properties in formal languages pose problems at the frontier of computer science, computational linguistics and computational group theory.
WebApr 14, 2024 · There exist one-dimensional commutative formal groups of arbitrary height, so most of these cannot be integrated. (This is a well-known fact in chromatic homotopy theory, related to the special status of K -theory and elliptic homology as opposed to Morava K -theories of height > 2 .)

The formal group law is called commutative if F ( x, y) = F ( y, x ). If R is torsionfree, then one can embed R into a Q -algebra and use the exponential and logarithm to write any one-dimensional formal group law F as F ( x, y) = exp (log ( x) + log ( y )), so F is necessarily commutative. [1] More generally, we have: Theorem. See more In mathematics, a formal group law is (roughly speaking) a formal power series behaving as if it were the product of a Lie group. They were introduced by S. Bochner (1946). The term formal group sometimes means … See more • The additive formal group law is given by $${\displaystyle F(x,y)=x+y.\ }$$ • The multiplicative formal group law is given by $${\displaystyle F(x,y)=x+y+xy.\ }$$ This rule can be understood as follows.
