Tensors are used in various parts of physics, both as abstract constructs in mathematical physics and for describing relations between quantities represented by matrices. ...more on Wikipedia about "Application of tensor theory in physics"

In mathematics, a Borel summation is a generalisation of the usual notion of summation of a series. In particular it gives a definition of a quantity that in many ways behaves formally like the sum, even if the series is in fact a divergent series. ...more on Wikipedia about "Borel summation"

Bred vectors are perturbations, related to Lyapunov vectors, that capture fast growing dynamical instabilities of the solution of a numerical model. They are used, for example, as initial perturbations for ensemble forecasting in numerical weather prediction. ...more on Wikipedia about "Bred vectors"

In mathematics, Floer homology refers to a family of homology theories which share similar characteristics and are believed by experts to be closely related. Some of these theories are due directly to Andreas Floer, while others are derived or inspired by his work. They are all modelled upon Morse homology on finite-dimensional manifolds, extending it to the case where the relevant Morse function has finite relative indices. The differentials all count some sort of pseudoholomorphic curves. ...more on Wikipedia about "Floer homology"

Mathematical physics is the scientific discipline concerned with "the application of mathematics to problems in physics and the development of mathematical methods suitable for such applications and for the formulation of physical theories" 1. ...more on Wikipedia about "Mathematical physics"

Perturbation theory comprises mathematical methods that are used to find an approximate solution to a problem which cannot be solved exactly, by starting from the exact solution of a related problem. Perturbation theory is applicable if the problem at hand can be formulated by adding a "small" term to the mathematical description of the exactly solvable problem. ...more on Wikipedia about "Perturbation theory"

Quantum groups are examples of quasitriangular Hopf algebras. There are various structures referred to as quantum groups. ...more on Wikipedia about "Quantum group"

A Hopf algebra, H, is quasitriangular if there exists an invertible element, R, of H \otimes H such that ...more on Wikipedia about "Quasitriangular"
