English translation of “A multidimensional generalization of the Wronskian”

Question

I am trying to generalize an algorithm for the construction of a certain linear combinations of functions $\boldsymbol{f}:x\in\mathbb{R}\mapsto \boldsymbol{f}(x)\in\mathbb{R}^n$ that utilizes Wronskian matrices, to the multidimensional version $\boldsymbol{f}:\boldsymbol{x}\in\mathbb{R}^m\mapsto\boldsymbol{f}(\boldsymbol{x})\in\mathbb{R}^n$ utilizing "some" multidimensional generalization of Wronskian matrices.

Some online research turned up A. I. Petrov, A multidimensional generalization of the Wronskian, Uspekhi Mat. Nauk, 1964, Volume 19, Issue 5, 194– 196, which is written in Russian language.

Question:

is there an English (or German) translation of the above linked paper freely available online?

What else can be recommended as freely accessible resources for the definition of multidimensional Wronskian matrices

Addendum:

from the statement "In the case of functions of several variables, there is no one determinant which may properly be taken as the generalization of the wronskian" in M. Green's 1916 paper The Linear Dependence of Functions of Several Variables, and Completely Integrable Systems of Homogeneous Linear Partial Differential Equations it became clear that questions about the multidimensional Wronskian are ill posed.

Answer 1

The solution to the mystery of how A. I. Petrov wrote a paper in 1964, when he was a student writing what appears to be his first paper in 1971, is that mathnet.ru has mistakenly taken his name to be A. I. Petrov, when in fact he is A. I. Perov, as you can see in the Wronskian paper. Moreover, Perov is still working at Voronezh State University, and I can send you his email address if you contact me at [email protected]. I don't know if he will help you, but the paper was part of a special collection of abstracts, so was not translated in the usual Uspekhi translations into English. The paper is pretty clearly translated using DeepL, so I don't think you really need a German or English reference.

Answer 2

A type of generalized Wronskian is used for the induction step in the proof of Roth's theorem in Diophantine approximation. There's a nice exposition in Schmidt's lecture note, for example, but undoubtedly it can be found in lots of other places. Roughly, the way that generalized Wronskians are used in the proof of Roth's theorem is to start with a polynomial $f(x_1,\ldots,x_r)$ and to construct a generalized Wronskian $W(f)$ that is the determinant of a matrix of partial derivatives (with controlled order) of $f$ having the property that $W(f)$ factors as $$ W\bigl(f(x_1,x_2,\ldots,x_r)\bigr) = g(x_1)h(x_2,\ldots,h_r). $$ This factorization is the key to doing an induction on the number of variables in the auxiliary polynomial.
