The International Mathematical Olympiad (IMO) is the World Championship Mathematics Competition for High School students and is held annually in a different country. The first IMO was held in 1959 in Romania, with 7 countries participating. It has gradually expanded to over 100 countries from 5 continents. The IMO Board ensures that the Physical and chemical properties of black carbon and organic matter from different combustion and photochemical sources using aerodynamic aerosol classification.

This implies that the outward normal on the bound-ary must be all contained in one of the two parallel distributions. Our result con rms the converse of the above observation. Theorem 1.1.
