On the constant roll complex scalar field inflationary models

Ali Mohammadi, Nahid Ahmadi, Mehdi Shokri

In this paper we wish to point out the possibility of using a complex scalar field in a constant roll inflationary model, as needed for observational viability. We extend the idea…

Product of sets on varieties in finite fields

Che-Jui Chang, Ali Mohammadi, Thang Pham +1

Let be a variety in and . It is known that if any line passing through the origin contains a bounded number of points from , then $|\prod(E)|=|\…

A Point-Conic Incidence Bound and Applications over

Ali Mohammadi, Thang Pham, Audie Warren

In this paper, we prove the first incidence bound for points and conics over prime fields. As applications, we prove new results on expansion of bivariate polynomial images and on…

Anti- Transformations And Complex Non-Hermitian -Symmetric Superpartners

Taha Koohrokhi, Sehban Kartal, Ali Mohammadi

We propose a new algebraic formalism for constructing complex non-Hermitian -symmetric superpartners by extending a conventional shape-invariant superpotential into t…

An energy decomposition theorem for matrices and related questions

Ali Mohammadi, Thang Pham, Yiting Wang

Given , we prove that there exist disjoint subsets such that and their additive and multiplicative energies satisf…

Attaining the exponent for the sum-product problem in finite fields

Ali Mohammadi, Sophie Stevens

We improve the exponent in the finite field sum-product problem from to , improving the results of Rudnev, Shakan and Shkredov. That is, we show that if $A\subset \math…

Almost orthogonal subsets of vector spaces over finite fields

Ali Mohammadi, Giorgis Petridis

We prove various results on the size and structure of subsets of vector spaces over finite fields which, in some sense, have too many mutually orthogonal pairs of vectors. In parti…

Improved bounds on Gauss sums in arbitrary finite fields

Ali Mohammadi

Let be a power of a prime and let be the finite field consisting of elements. We establish new explicit estimates on Gauss sums of the form $S_n(a) = \sum_{x…
