SUMMARY

The discussion focuses on generating whole number sequences for the equation (2x+3y)/(x+y) = e, where e represents Euler's number. It establishes that the ratio x/y can be expressed as (e-3)/(2-e), allowing for the derivation of rational sequences that converge to this value. By setting y to powers of ten (1, 10, 100, etc.), participants suggest a straightforward method for determining corresponding x values. Additionally, the use of continued fractions is proposed as an alternative approach for achieving convergence.

PREREQUISITES
  • Understanding of rational sequences and convergence

How can one generate the sequence of whole numbers x and y which converge upon the equality

(2x+3y)/(x+y) = e

?

(2x+3y)/(x+y) = e gives x/y = (e-3)/(2-e), so it suffices to find a sequence of rationals which converges to (e-3)/(2-e). If the decimal expansion of (e-3)/(2-e) is given, then we can just set y = 1, 10, 100, 1000, 10000, ... and make the obvious choice for x.

Same as above- except use continued fractions for x/y=(e-3)/(2-e)
 
I am studying the mathematical formalism behind non-commutative geometry approach to quantum gravity. I was reading about Hopf algebras and their Drinfeld twist with a specific example of the Moyal-Weyl twist defined as F=exp(-iλ/2θ^(μν)∂_μ⊗∂_ν) where λ is a constant parametar and θ antisymmetric constant tensor. {∂_μ} is the basis of the tangent vector space over the underlying spacetime Now, from my understanding the enveloping algebra which appears in the definition of the Hopf algebra...
