What is Distributivity (order theory)?

The membrane theory of shells, or membrane theory for short, describes the mechanical properties of shells when twisting and bending moments are small enough to be negligible. The spectacular simplification...

Viability theory is an area of mathematics that studies the evolution of dynamical systems under constraints on the system state. It was developed to formalize problems arising in the study...

In mathematics, differential Galois theory studies the Galois groups of differential equations.

In mathematics, the fundamental theorem of Galois theory is a result that describes the structure of certain types of field extensions in relation to groups. It was proved by Évariste...

In mathematics, computational group theory is the study ofgroups by means of computers. It is concernedwith designing and analysing algorithms anddata structures to compute information about groups. The subjecthas attracted...

In category theory, a Lawvere theory is a category that can be considered a categorical counterpart of the notion of an equational theory.

In mathematics, chromatic homotopy theory is a subfield of stable homotopy theory that studies complex-oriented cohomology theories from the "chromatic" point of view, which is based on Quillen's work relating...

In computational complexity theory of computer science, the structural complexity theory or simply structural complexity is the study of complexity classes, rather than computational complexity of individual problems and algorithms....

Applied category theory is an academic discipline in which methods from category theory are used to study other fields including but not limited to computer science, physics , natural language...

Many first principles in quantum field theory are explained, or get further insight, in string theory.
