Plant-pathogen-herbivore model describe interaction between plants, pathogens and herbivores. Plants are invaded by pathogens and herbivores while the herbivores are harvested by natural enemies such as predators and human. On the other hand, the abundance of food does not guaran...

In this study, we derive a new representation for the Euler-Mascheroni constant and present various expressions for the classical Euler-Mascheroni constant related to the Riemann zeta function. Also, we proved that \(\gamma\) is not algebraic if the Schanuel conjecture is true.

Let Uq(f(K, J)) be an extended quantum enveloping algebra associated to sl2. In this paper, we display an equitable presentation for Uq(f(K, J)), in which all generators appear on a more equal footing. We also show that the equitable generators Y and Z are not invertible. Moreove...

In this paper, we have proved that the probability density function \(f(t)\) considered as a distribution has a Cauchy representation in \(O_\alpha^{\prime}\). The distribution space \(O_\alpha^{\prime}\) is intermediate space between \(E^{\prime}\) and \(D^{\prime}\).

The incompleteness of set theory \(Z F C\) leads one to look for natural nonconservative extensions of \(Z F C\) in which one can prove statements independent of \(Z F C\) which appear to be "true". One approach has been to add large cardinal axioms.Or, one can investigate second...
