    en.wikipedia.org/wiki/Basic_theorems_in...

    In mathematics, there are several theorems basic to algebraic K-theory. Throughout, for simplicity, we assume when an exact category is a subcategory of another exact category, we mean it is strictly full subcategory (i.e., isomorphism-closed.)

  3. Operator theory - Wikipedia

    en.wikipedia.org/wiki/Operator_theory

    In mathematics, operator theory is the study of linear operators on function spaces, beginning with differential operators and integral operators.The operators may be presented abstractly by their characteristics, such as bounded linear operators or closed operators, and consideration may be given to nonlinear operators.

    For example, the specification "" is an almost literal translation of the maximum segment sum problem, [6] but running that functional program on a list of size will take time () in general. From this, Bird computes an equivalent functional program that runs in time O ( n ) {\displaystyle {\mathcal {O}}(n)} , and is in fact a functional version ...

    en.wikipedia.org/wiki/K-space_(functional_analysis)

    In mathematics, more specifically in functional analysis, a K-space is an F-space such that every extension of F-spaces (or twisted sum) of the form is equivalent to the trivial one [1] where is the real line.

  6. Mabuchi functional - Wikipedia

    en.wikipedia.org/wiki/Mabuchi_functional

    The Mabuchi functional is an analogy of the log-norm functional of the moment map in geometric invariant theory and symplectic reduction. [2] The Mabuchi functional appears in the theory of K-stability as an analytical functional which characterises the existence of constant scalar curvature Kähler metrics.

    If you're starting from ground zero (a.k.a. you don't have an existing, consistent cardio routine), Carnation recommends aiming for 20 minutes of moderate-intensity cardio a day, four days per week.

  9. Category theory - Wikipedia

    en.wikipedia.org/wiki/Category_theory

    The Yoneda lemma is one of the most famous basic results of category theory; it describes representable functors in functor categories. Duality: Every statement, theorem, or definition in category theory has a dual which is essentially obtained by "reversing all the arrows".
