Basic Facts for Basic Science

Overall, this outstanding text should soon become recognized as the definitive reference for the diagnosis and management of ocular trauma. The tall, narrow shape of Basic Facts for Basic Science suggests that perhaps the author intended that it be put into the pocket of one's lab coat; perhaps not, but this book is certainly appropriate for the shelf of any laboratory and for the office of any...

Basic Facts about Expander Graphs

In this survey we review basic facts regarding expander graphs that are most relevant to the theory of computation.

2007 P . Achar Basic Facts on Sheaves

(1) (restriction) if U ⊂ V ⊂ W , then ρWU = ρV U ◦ ρWV (2) (gluing) if {Vi} is an open covering of U , and we have si ∈ F(Vi) such that for all i, j, ρVi,Vi∩Vj (si) = ρVj ,Vi∩Vj (sj), then there exists a unique s ∈ F(U) such that ρU,Vi(s) = si for all i. If one omits the gluing condition from the above definition, one has a presheaf of abelian groups. Elements of F(U) are called sections of F o...

Basic Facts about Inaccessible and Measurable Cardinals

Let X be an infinite set. One can check that X is infinite. The scheme ElemProp deals with a non empty set A , a set B, and a unary predicate P , and states that: P [B] provided the parameters meet the following requirement: • B ∈ {y;y ranges over elements of A : P [y]}. For simplicity, we use the following convention: N is a cardinal number, M is an aleph, X is a non empty set, Y , Z, Z1, Z2, ...
