The central concern of the symposium was to focus upon areas of importance in contemporary mathematical research which can be seen as descended in some way from the ideas and tendencies put forward by Hilbert in his speech at the International Congress of Mathematicians in Paris in The Organizing Committee's basic objective was to obtain as broad a representation of significant mathematical research as possible within the general constraint of relevance to the Hilbert problems.

The Committee consisted of P. Bateman secretary , F. Browder chairman , R.

Buck, D. Lewis, and D. The volume contains the proceedings of that symposium and includes papers corresponding to all the invited addresses with one exception. One of these problems, the fifth, was to challenge mathematicians for over half of the twentieth century. Hilbert's fifth problem was phrased as such: "Can the assumption of differentiability for functions defining a continuous transformation group be avoided? These individual terms can be confusing and will be explained further before going on. A topological group is any group of numbers that are points in topological space for which group operations are continuous.

An example of topological groups is the set of real numbers where addition or subtraction are group products. Another is the set of rigid motions that a group of points can take in Euclidean space that is, space that follows the geometry described by Euclid [c. In this case, if one visualizes a rotating block of wood as representing a group of points, these points would form a topological group because they stay together as the block rotates in space. A manifold is another concept entirely.

### 1. Cantor's problem of the cardinal number of the continuum

Put most simply, a manifold is a surface with a given number of dimensions. For example, the surface of a sphere is a manifold with two dimensions because there are only two directions an object on that surface can move. The fact that the surface encloses a three-dimensional structure is irrelevant in this case.

An analytic manifold can be mathematically described. One interesting property of manifolds is that, in Euclidean space, small patches appear to be flat and can be treated as such. For example, even though Earth is a sphere, we treat a floor as flat because, for all practical purposes, it looks that way to us at our scale.

This makes it possible to use "ordinary" mathematics to describe small sections of the manifold and any shapes or curves that might be drawn on them. The final term to describe is Lie algebra or Lie group.

In general, a group is a set either finite or infinite of items called operands that can be combined via some sort of mathematical operation to form defined products. A Lie group is a special type of group in which the underlying space is an analytic manifold and, on that manifold, group operations are analytic that is, they are described by equations. At this point, too, it must be noted that a Lie group is not, in the strictest sense, a group at all. It only takes a minute to sign up. What was the main error in the proof of the second part of the 16th Hilbert problem by Petrovski and Landis?

Please see this related post and also the following post. For Mathematical development around this historical problem please see this paper. Added : According to their method, what of the following two statements are true? Some technical and historical aspects of these foliations are explained here. However in this linked paper there is no an explicit explianation about the "error".

According to the video of lecture of Ilyashenko, provided in the answer to this question by Andrey Gogolev, we ask:.

What is the fate of the "persistence problem" which is mentioned by Ilyashenko? How it can be revised to become a true statement? Can every leaf be parametrized by an entire map?

## Hilbert’s problems

According to comments and answers to this question, we undrestand there is no a written paper which explains the error , explicitly. Why really this is the case? This seems annoyingly hard to find! On the plus side, explicit constructions of quadratic vector fields with four limit cycles - even really nice ones! I can't seem to find the simplest examples, though, which would presumably be the nicest for trying to figure out without access to the paper itself what the error was. Ilyashenko says he and Novikov found the error "in the early 60s" pg. Backing this up, Shi's abstract mentions that the question "Is there a quadratic vector field with exactly 4 limit cycles?

Thus, although I'd imagine more specific discussion of when the error was noticed and maybe even what it was! Ilyashenko explaines very well the strategy and the main error of Petrovski-Landis in this lecture:.
