Preservation of elementarity by tensor products of tracial von Neumann algebras
Ilijas Farah, Saeed Ghasemi
Tensoring with type I algebras preserves elementary equivalence in the category of tracial von Neumann algebras. The proof involves a novel and general Feferman--Vaught-type theore…
A lower bound of the energy of non-singular graphs in terms of average degree
Saieed Akbari, Hossein Dabirian, S. Mahmood Ghasemi
Let be a graph of order with adjacency matrix . The \textit{energy} of graph , denoted by , is defined as the sum of absolute value of eigenvalues…
Corona Rigidity
Ilijas Farah, Saeed Ghasemi, Andrea Vaccaro +1
We give a unified overview of the study of the effects of additional set theoretic axioms on quotient structures. Our focus is on rigidity, measured in terms of existence (or rathe…
A class of AF-algebras up to universal UHF-algebra stability
Saeed Ghasemi
We will show that separable unital AF-algebras whose Bratteli diagrams do not allow converging two nodes into one node, can be classified up to the tensor product with the universa…
Strongly self-absorbing -algebras and Fraïssé limits
Saeed Ghasemi
We show that the Fraïssé limit of a category of unital separable -algebras which is sufficiently closed under tensor products of its objects and morphisms is strongly self-abs…
Universal AF-algebras
Saeed Ghasemi, Wiesław Kubiś
We study the approximately finite-dimensional (AF) -algebras that appear as inductive limits of sequences of finite-dimensional -algebras and left-invertible embeddings.…
