#### Compactified Jacobians of integral curves with double points

(Massachusetts Institute of Technology, 1997)

#### Noncommutative ring spectra

(Massachusetts Institute of Technology, 2006)

Let A be an Ax ring spectrum. We give an explicit construction of topological Hochschild homology and cohomology of A using the Stasheff associahedra and another family of polyhedra called cyclohedra. Using this construction ...

#### Topological Hochschild homology of twisted group algebras

(Massachusetts Institute of Technology, 2006)

Let G be a group and A be a ring. There is a stable equivalence of orthogonal spectra ... between the topological Hochschild homology of the group algebra A[G] and the smash product of the topological Hochschild homology ...

#### On the Selmer groups of elliptic curves in quadratic twist families

(Massachusetts Institute of Technology, 1995)

#### Multiplicity-free Hamiltonian actions and existence of invariant Kähler structure

(Massachusetts Institute of Technology, 1996)

#### The strongly attracting character of large amplitude nonlinear resonant acoustic waves without shocks : a numerical study

(Massachusetts Institute of Technology, 1996)

#### Parabolic equations without a minimum principle

(Massachusetts Institute of Technology, 2007)

In this thesis, we consider several parabolic equations for which the minimum principle fails. We first consider a two-point boundary value problem for a one dimensional diffusion equation. We show the uniqueness and ...

#### Adaptive protocols for the quantum depolarizing channel

(Massachusetts Institute of Technology, 2007)

In the first part, we present a family of entanglement purification protocols that generalize four previous methods, namely the recurrence method, the modified recurrence method, and the two methods proposed by Maneva-Smolin ...

#### Three-dimensional solitary waves in dispersive wave systems

(Massachusetts Institute of Technology, 2006)

Fully localized three-dimensional solitary waves, commonly referred to as 'lumps', have received far less attention than two-dimensional solitary waves in dispersive wave systems. Prior studies have focused in the long-wave ...

#### Spaces of algebra structures and cohomology of operads

(Massachusetts Institute of Technology, 1996)
