I'd like to know what the expression due to means. For example:
This proof is due to X and Y
Can we say
This proof is attributed to X and Y?
I'd say the simplest translation might be
but, in case that is still too ambiguous, it means:
1. caused by or ascribable to.
"his death was not due to any lack of care"
2. because of; owing to.
"he had to withdraw due to a knee injury"
Your guess at its meaning is not quite correct, really it would be:
attributable to X and Y
