In summary, the conversation discusses the integral equality \int_{-\infty}^{\infty}dxf(x)x^{a}\int_{-\infty}^{\infty}g(x+y)y^{ib}=0 and the possibility of finding a solution for a and b. The conversation becomes confusing as the speaker suggests that if the integrals are equal, then x and y must have the same exponent, but then contradicts themselves by proposing a solution for a and b. The conversation ends with questioning the validity of the speaker's logic and mentioning the Riemann Hypothesis.

Integral equality...

let be a and b real numbers..and let be the integral...

[tex]\int_{-\infty}^{\infty}dxf(x)x^{a}\int_{-\infty}^{\infty}g(x+y)y^{ib}=0 [/tex] so if this is zero also will be its conjugate:

[tex]\int_{-\infty}^{\infty}dxf(x)x^{a}\int_{-\infty}^{\infty}g(x+y)y^{-ib}=0 [/tex] now let,s suppose we would have that (1-a,-b) is also a zero so:

[tex]\int_{-\infty}^{\infty}dxf(x)x^{1-a}\int_{-\infty}^{\infty}g(x+y)y^{-ib}=0 [/tex] then my conclusion is that 1-a=a a=1/2 and there is no other solution.. :biggrin: :zzz: :biggrin: :biggrin: :biggrin: :biggrin:

You've *somehow* decided that if your integrals are equal then x must have the same exponent? I don't even know where to begin with what's wrong here, but by your logic shouldn't the same be true for y then, so b=0? Please, tell me this is a joke.

Have you been reading some of the horrible "proofs" of the Riemann Hypothesis you find online? This looks awfully familiar.

Are you integrating over y in the second integral? x? A nonexistent variable?
 

What is integral equality?

Integral equality is a concept in mathematics that refers to the idea that two integrals with the same limits of integration and integrands are equal.

Why is integral equality important?

Integral equality is important because it allows us to manipulate integrals in various ways, making it easier to solve complex problems and equations.

What are some common applications of integral equality?

Integral equality has many applications in physics, engineering, and other areas of mathematics. It is commonly used in calculating areas, volumes, and finding the center of mass of an object.

How can integral equality be used to solve integrals?

By using integral equality, we can convert difficult integrals into simpler forms that are easier to solve. This is especially useful in cases where we need to integrate functions that are not easily integrable.

Are there any limitations to integral equality?

Yes, integral equality only applies to indefinite integrals and not definite integrals. It also does not hold for all functions, as there are some functions that cannot be integrated using standard techniques.
