Green's functions are a traditional technique for solving inhomogeneous differential equations which has found several applications in pure and applied science, as, for instance, in Electrodynamics or Quantum Mechanics (Hassani, 2002). Given a one-dimensional linear differential operator, x , and a set of boundary conditions, the solution to the inhomogeneous differential equation ) x ( g ) x (...

We obtain asymptotic formulas for the sums $\sum_{n_1,\ldots,n_k\le x} f((n_1,\ldots,n_k))$ and $ \sum_{n_1,\ldots,n_k\le f([n_1,\ldots,n_k])$ involving gcd lcm of integers $n_1,\ldots,n_k$, where $f$ belongs to certain classes additive arithmetic functions. In particular, we consider generalized omega function $\Omega_{\ell}(n)= \sum_{p^\nu \mid\mid n} \nu^{\ell}$ investigated by Duncan (1962)...

Contaminated food is responsible for a significant amount of illnesses. In Morocco, it has become a worrying concern. Numerous awareness campaigns are conducted to warn the population against the risks of such scourge in ways that will prevent foodborne illness. Lawful commissions are in charge of examining and ensuring food safety in production and catering establishments, in addition to the a...
