This person's namesake function is a generalization of length to integer-graded modules over graded rings. This thinker's namesake symbol returns 1 if a three-variable quadratic equation is solvable with its two p-adic inputs as coefficients. This is the first namesake of a type of operator useful in the study of Fredholm integral equations with symmetric kernels; the study of such equations is known as his and Schmidt's namesake theory and those operators are also bounded in his and Schmidt's namesake norm. Like Peano,

Like Peano, this mathematician has a namesake curve of limiting Hausdorf dimension 2 which is his namesake square-filling curve. This mathematician names complete inner product spaces equipped with complete L-2 norms, all of which are Banach spaces. For 10 points, name this mathematician perhaps better known for posing twenty-three important problems in mathematics.
