Encyclopedia of Applied and Computational Mathematics EACM is a comprehensive reference work covering the vast field of applied and computational mathematics. Applied mathematics itself accounts for at least 60 per cent of mathematics and the emphasis on computation reflects the current and constantly growing importance of computational methods in all areas of applications. EACM emphasizes the strong links of applied mathematics with major areas of science such as physics chemistry biology and computer science as well as specific fields like atmospheric ocean science. In addition the mathematical input to modern engineering and technology form another core component of EACM
