Hyperbolic 3-manifolds with uniform spectral gap for coclosed 1-forms
Amina Abdurrahman, Anshul Adve, Vikram Giri +2
We study two quantifications of being a homology sphere for hyperbolic 3-manifolds, one geometric and one topological: the spectral gap for the Laplacian on coclosed 1-forms and th…

CM Method and Expansion of Numbers
A Abdurrahman
We show that an iterative method for computing the center of mass (CM) of q units of mass, placed on a unit interval [0, 1] along the x- axis, give rise to a simple procedure for e…

Ward-like Operator in the comma theory
A Abdurrahman
The construction of the Ward-like operator of the interacting string field theory presented by Witten, in terms of the half-string (comma) oscillator modes, is completed.
