-Symplectic Manifolds and

Ahmad Reza Haj Saeedi Sadegh

We study the geometric quantization of -symplectic manifolds using the integrability of Lie algebroids. Using a groupoid index, we define a quantization for -symplectic m…

Fredholm -Filtration of Fredholm Groups

Ahmad Reza Haj Saaedi Sadegh, Jody Trout

In this short note, we show that some well-known filtrations of infinite dimensional groups of Fredholm operators associated to certain perturbation classes are, in fact, Fredholm…

On Deformation Spaces, Tangent Groupoids and Generalized Filtrations of Banach and Fredholm Manifolds

Ahmad Reza Haj Saeedi Sadegh, Jody Trout

We extend the deformation to the normal cone and tangent groupoid constructions from finite-dimensional manifolds to infinite-dimensional Banach and Fredholm manifolds. Next, we ge…

A gluing formula for the -valued index of odd symmetric operators

Maxim Braverman, Ahmad Reza Haj Saeedi Sadegh, Junrong Yan

We investigate Dirac-type operator on involutive manifolds with boundary with symmetry, which forces the index of to vanish. We study the secondary -valued index of el…

The Z_2-valued spectral flow of a symmetric family of Toeplitz operators

Maxim Braverman, Ahmad Reza Haj Saeedi Sadegh

We consider families of self-adjoint operators with symmetry that causes the spectral flow of the family to vanish. We study the secondary -valued spectral flo…

A Fueter Operator for 3/2-spinors

Ahmad Reza Haj Saeedi Sadegh, Minh Lam Nguyen, Jesus Sanchez

We show the non-compactness of the moduli space of solutions with a uniform bound on the curvatures of the monopole equations for -spinors on a closed 3-manifold is equivalent…

On the Z_2-valued index of elliptic odd symmetric operators on non-compact manifolds

Maxim Braverman, Ahmad Reza Haj Saeedi Sadegh

We investigate elliptic operators with a symmetry that forces their index to vanish. We study the secondary index, defined modulo 2. We examine Callias-type operators with this sym…

The three-dimensional Seiberg-Witten equations for 3/2-spinors: a compactness theorem

Ahmad Reza Haj Saeedi Sadegh, Minh Lam Nguyen

The Rarita-Schwinger-Seiberg-Witten (RS-SW) equations are defined similarly to the classical Seiberg-Witten equations, where a geometric non-Dirac-type operator replaces the Dirac…

Deformation Spaces, Rescaled Bundles and the Kirillov Character Formula

Maxim Braverman, Ahmad Reza Haj Saeedi Sadegh

In this paper, we construct a smooth vector bundle over the deformation to the normal cone through a rescaling of a vector bundle , which generalizes the…

Connes-Moscovici Residue Cocycle For Some Dirac-Type Operators

Ahmad Reza Haj Saeedi Sadegh, Yiannis Loizides, Jesus Sanchez

The residue cocycle associated to a suitable spectral triple is the key component of the Connes-Moscovici local index theorem in noncommutative geometry. We review the relationship…

Euler-like vector fields, deformation spaces and manifolds with filtered structure

Ahmad Reza Haj Saeedi Sadegh, Nigel Higson

The first purpose of this note is to comment on a recent article of Bursztyn, Lima and Meinrenken, in which it is proved that if M is a smooth submanifold of a manifold V, then the…

Relative-partitioned index theorem

Moin Karami, Mostafa E. Zadeh, Ahmad H. S. Sadegh

It seems that the index theory for non-compact spaces has found its ultimate formulation in realm of coarse spaces and -theory of related operator algebras. Relative and partiti…
