Counting minimal reactions with specific conditions in mathbbR 4{mathbb{R} ^4}

摘要

We give the sharp lower bound on the number of minimal reactions when no “parallel” species (isomers or multiples) are allowed and all the species are built up from at most four kinds of atoms in Theorem 16. This continues the investigations in Kumar and Pethő (Intern Chem Eng 25:767–769, 1985) through Szalkai and Laflamme (Electr J Comb 5(1), 1998) which results we briefly summarize in the first Section.
