Secular function section
This section is completely incomprehensible to me. What on earth is "matrix tearing and gruing" and "determinant of a matrix with a shift"? Where do the poles of the secular function come from? A polynomial has no poles.
- I agree. Everything after the first paragraph, particularly the middle of this section, is very poorly written. I can only assume it was written by a non-native speaker of English or, like you said, as a joke. It would be great if someone familiar with secular functions could re-write this section more clearly. 126.96.36.199 (talk) 18:42, 14 October 2011 (UTC)
Article mentions two conventions, justifies settling on one, then uses the other in the tail of the article. Perhaps settle on one convention (the one argued for at the beginning) used throughout except in one section which explains the other, gives corresponding forms, show how to interconvert, so that all "alternative" convention is restricted to that section.
An explicit expansion of the polynomial (with the alternative form in the "alternative" section) showing the terms/coefficients referred to later might help clear things up. — Preceding unsigned comment added by 188.8.131.52 (talk) 17:13, 8 May 2013 (UTC)
instead of ?
In the entry text I read:
After consulting the entry about exterior algebra (which is referred to by the text), I noticed that the symbol is used there.
Characteristic of what?
The current entry text contains:
"When the characteristic is 0 it may alternatively be computed as a single determinant, that of the k×k matrix, [...]"
Could someone tell us the characteristic of what is meant here? (I did follow the link to "characteristic" (algebra) but that seems to deal with rings and fields, and the connection to the quoted statement is not clear to me.Redav (talk) 14:01, 28 November 2020 (UTC)
- The connection is that the facor 1/k! makes no sense in non-zero characteristice. However I have edited the article for clarification. D.Lazard (talk) 14:43, 28 November 2020 (UTC)
