Natural Logarithm of Convolution

Click For Summary
The discussion centers on the application of logarithmic properties to the convolution of two functions, specifically questioning if ln(x*y) equals ln(x) + ln(y). It clarifies that convolution operates on functions rather than simple variables, resulting in another function. Consequently, the logarithmic properties do not hold true for convolutions, as they involve integrals rather than direct multiplication of numbers. The initial query reflects a misunderstanding of the mathematical operations involved. Ultimately, the properties of logarithms do not apply to convolutions of functions.

If I have a convolution of two variables, say x * y, and I take the natural logarithm of this operation, ln(x*y), do the same properties of logarithms apply?

So, does ln(x*y) = ln(x)+ln(y) ?

In your notation, what are x, y, x*y and ln? Usually ln(x) is the natural log of a number (x).

I'm afraid your question doesn't make any sense as stated. The convolution operation is an operation on two functions, not two variables, and it gives another function. And if you ask the same question for functions, the answer is no.

I realize that now since a convolution is an integral... just wishful thinking on my part I guess.
 
Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
