On a new reformulation of Hadwiger's conjecture
Assuming that every proper minor closed class of graphs contains a maximum with respect to the homomorphism order, we prove that such a maximum must be homomorphically equivalent to a complete graph. This proves that Hadwiger’s conjecture is equivalent to saying that every minor closed class of graphs contains a maximum with respect to homomorphism order. Let F be a finite set of 2-connected gr...

A Reformulation of the Hoop Conjecture
A reformulation of the Hoop Conjecture which avoids the use of any foliations as well as ill-defined notions of “encircled mass” and “circumference of a body” is presented. The new formulation is based on the concept of trapped circle, which is well-defined, geometrically sound, and physically relevant. With the new formulation, the problems of severe compactness in every spatial direction, and...
متن کاملon the comparison of keyword and semantic-context methods of learning new vocabulary meaning
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
15 صفحه اولA Sheaf-theoretic Reformulation of the Tate Conjecture
We present a conjecture which unifies several conjectures on motives in characteristic p. Introduction In a talk at the June 1996 Oberwolfach algebraic K-theory conference, I explained that, in view of Voevodsky’s proof of the Milnor conjecture, the Bass conjecture on finite generation of K-groups of regular schemes of finite type over the integers implies the rational Beilinson-Soulé conjectur...
