Paradox on the Countable Axiom of Choice
Babak Jabbar Nezhad
Bishop's constructive mathematics school rejects the Law of Excluded Middle, but instead vastly makes use of weaker versions of the Choice. In this paper we pioneer an example, whi…
A Paradox on the Law of Excluded Middle in the framework of category of set
Babak Jabbar Nezhad
In this paper, we present a paradox arising from the acceptance of the Law of Excluded Middle (LEM) within classical mathematics. Specifically, we construct a nonzero analytic func…
Equations of the multi-Rees algebra of fattened coordinate subspaces
Babak Jabbar Nezhad
In this paper we describe the equations defining the multi-Rees algebra , where the ideals are generated by subsets of $x_1,\dots…
Multi-Rees algebras on principal ideal rings
Babak Jabbar Nezhad
When is a Noetherian ring and we have a family of ideals in which every ideal contains at least one nonzero divisor, then it is already known that the defining ideal of the mul…
Koszul multi-Rees algebras of principal -Borel Ideals
Michael DiPasquale, Babak Jabbar Nezhad
Given a monomial in a polynomial ring and a subset of the variables of the polynomial ring, the principal -Borel ideal generated by is the ideal generated by all mon…
