We find analogous equations in the theory of cracks.
Such equations play a role in the theory of differential equations.
Using matrix methods, he also contributed fundamentally to the theory of difference equations.
Hairer won for his "outstanding contributions to the theory of stochastic partial differential equations", which contain terms that are inherently random.
Lévy contributed to the theory of probability, functional analysis, and other analysis problems, principally partial differential equations and series.
I look at everything in my life as trying to find the single equation, the theory of everything.
His major contributions were in elliptic functions, the theory of algebraic equations, and the theory of algebraic numbers.
What is more, the class of equations to which the theory applies contains several that are of central interest in mathematics and science.
The history of the theory of equations belies the view that mathematics is subject to almost automatic technical development.
The proof of solvability is based on the theory of singular integral equations, Wiener-Hopf equations and Fredholm integral equations.
They hold a banquet annually, and discuss such subjects as the theory of function, differential equations, etc.
