Substitution of two or four carbon atoms by nitrogen in the corannulene molecule as a carbon nanostructure was done and the obtained structures were optimized at MP2/6-31G(d) level of theory. Calculations of the nucleus-independent chemical shift (NICS) were performed to analyze the aromaticity of the corannulene rings and its derivatives upon doping with N at B3LYP/6-31G(d) level of theory.

Motivated by the study of $(m,n)$-quasitilted algebras, which are piecewise hereditary algebras obtained from quasitilted global dimension 2 a sequence (co)tiltings involving $n-1$ tilting modules and $m-1$ cotilting modules, we intr
