Constructing Essential Laminations In 2-Bridge Knot Surgered 3-Manifolds, Ramin Naimi Dec 1996

Constructing Essential Laminations In 2-Bridge Knot Surgered 3-Manifolds, Ramin Naimi

Ramin Naimi

A nontrivial knot that can be drawn with only two relative maxima in the vertical direction is called a 2-bridge knot, and one that can be drawn on a torus is called a torus knot. Loosely speaking, a lamination in a manifold M is a foliation of M, except that it can have a nonempty open complement in M, and very loosely speaking, the lamination is essential if each leaf of it L is incompressible, i.e. inclusion of L into M induces an injective homomorphism from π1(L) into π1(M). Our main result is: Theorem 2. Every 3-manifold obtained by surgery …


An Alternative Dunford-Pettis Property, Walden Freedman Dec 1996

An Alternative Dunford-Pettis Property, Walden Freedman

Walden Freedman

An alternative to the Dunford-Pettis Property, called the DPI-property, is introduced. Its relationship to the Dunford-Pettis Property and other related properties is examined.

Mathematical Instantons With Maximal Order Jumping Lines, Prabhakar Rao Dec 1996

Mathematical Instantons With Maximal Order Jumping Lines, Prabhakar Rao

Prabhakar Rao

A mathematical instanton bundle on P3 (over an algebraically closed field) is a rank two vector bundle ℰ on P3 with c1 = 0 and with H0() = H1((2)) = 0. Let c2() = n. Then n > 0. A jumping line of ℰ of order a, (a > 0), is a line ℓ in P3 on which splits as 𝒪(a) ⊕𝒪(a). It is easy to see that the jumping lines of ℰ all have order ≤ n. We will say that ℰ has a maximal order jumping line if it …
