Information: - Gilbert Ames Bliss , ( 9 May 1876 -- 8 May 1951 ) , was an American mathematician , known for his work on the calculus of variations . - Mathematical analysis is the branch of mathematics dealing with limits and related theories, such as differentiation, integration, measure, infinite series, and analytic functions. - In mathematics, a real number is a value that represents a quantity along a line. The adjective "real" in this context was introduced in the 17th century by Rene Descartes, who distinguished between real and imaginary roots of polynomials. - Calculus of variations is a field of mathematical analysis that deals with maximizing or minimizing functionals, which are mappings from a set of functions to the real numbers. Functionals are often expressed as definite integrals involving functions and their derivatives. The interest is in "extremal" functions that make the functional attain a maximum or minimum value or "stationary" functions those where the rate of change of the functional is zero. What object entity has the relation of 'field of work' with the subject 'gilbert ames bliss'? Choices: - calculus of variations - mathematical analysis - mathematics
**Answer**
