Functional Analysispresents an original approach to a field that first appeared in the beginning of last century in old mathematical fields like variational calculus, theory of partial differential equations, numerical analysis and theory of integral equations. Functional analysis can be considered as a generalization and a geometrical interpretation of the mathematical analysis (calculus).

• Presents an original approach to functional analysis
• Helps readers determine and interpret the different facets of mathematical analysis (calculation)
• Explains older mathematical domains (variational calculus, the theory of partial differential equations, numerical analysis and the theory of integral equations)
