Homework Help Overview

The discussion revolves around a conjecture related to transcendental numbers, specifically examining the relationships between the sums and differences of such numbers. The original poster is exploring whether the conjecture that if u and v are transcendental numbers, and u-v is not algebraic, then u+v must be transcendental, holds true. They are particularly interested in applying this conjecture to prove that all numbers of the form log_e(m), where m is a natural number greater than 1, are transcendental.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to establish a connection between the algebraic nature of the difference and the transcendental nature of the sum of two numbers. They also reference the Lindemann-Weierstrass theorem as a potential avenue for supporting their conjecture.

Discussion Status

The discussion includes an acknowledgment of a counterexample provided by another participant, which raises questions about the validity of the original conjecture. Some participants are exploring the implications of the Lindemann-Weierstrass theorem in relation to the conjecture, indicating a productive direction in the discussion.

Contextual Notes

The original poster notes their intention to prove a specific property of logarithmic forms, which may impose constraints on the types of numbers being considered. The discussion also reflects uncertainty regarding the correctness of the conjecture itself.

Homework Statement


I want to try to prove something, but I don't even know if it's right. So I thought I would come to you for help. The conjecture is below:

For two transcendental numbers u and v, if u-v is not algebraic, then u+v is transcendental.

Homework Equations


The Attempt at a Solution



Now, I know that if u-v IS algebraic, then u+v is NOT transcendental. But I don't think that's what I'm looking for...

Note: I'm using this in an attempt at a proof that all numbers of the form [itex]log_e(m)[/itex], where m is a natural number greater than 1, are transcendental.

u=pi, v=(-pi). u-v is transcendental, u+v isn't.
 
Ah, I see. Thanks.
