Web19 okt. 2024 · The mathematical field of information theory attempts to mathematically describe the concept of “information”. In the first two posts, we discussed the concepts of self-information and information entropy. In this post, we step through Shannon’s Source Coding Theorem to see how the information entropy of a probability distribution … Web6 jan. 2024 · Helly’s theorem is one of the most well-known and fundamental results in combinatorial geometry, which has various generalizations and applications. It was first proved by Helly [12] in 1913, but his proof was not published until 1923, after alternative proofs by Radon [17] and König [15].

WebOne of the most important generalizations of Helly’s theorem is the fractional Helly theorem, showing that if we only assume a positive fraction of the (d+ 1)-tuples are intersecting, then there is still a large intersecting subfamily. More precisely, the fractional Helly theorem asserts that for every positive integer d, there exists a function WebHelly theorems, we need to come up with an objective function. Section 2 formally defines these notions. In section 3 we begin by showing that there is a Helly theorem about the constraint family of every fixed dimensional GLP problem; that is, the class of problems for which there are Helly theorems includes the fixed dimensional GLP problems. college schedule blocker

We consider quantitative versions of Helly-type questions, that is, instead of finding a point in the intersection, we bound the volume of the intersection. Our first main result is a quantitative version of the Fractional Helly Theorem of Katchalski and Liu, the second one is a quantitative version of the ( p , q )-Theorem of Alon ...
