A contraction mapping has at most one fixed point. Moreover, the Banach fixed-point theorem states that every contraction mapping on a non-empty complete metric space has a unique fixed point, and that for any x in M the iterated function sequence x , f ( x ), f ( f ( x )), f ( f ( f ( x ))), ... converges to the fixed point.
In psychology, a construct, also called a hypothetical construct or psychological construct, is a tool used to facilitate understanding of human behavior. A psychological construct is a label for a domain of behaviors. Behavioral sciences use constructs such as conscientiousness, intelligence, political power, self-esteem, and group culture.
Two cases of two interrelated geons, What does the reader imagine in each case? There are 4 essential properties of geons: View-invariance: Each geon can be distinguished from the others from almost any viewpoints except for “accidents” at highly restricted angles in which one geon projects an image that could be a different geon, as, for example, when an end-on view of a cylinder can be a ...
This primordial initial contraction, forming a "vacant space" (חלל הפנוי, ḥalal hapanuy) into which new creative light could beam, is denoted by general reference to the tzimtzum. In Kabbalistic interpretation, tzimtzum gives rise to the paradox of simultaneous divine presence and absence within the vacuum and resultant Creation.
Psychology is the scientific study of mind and behavior. [1] [2] Its subject matter includes the behavior of humans and nonhumans, both conscious and unconscious phenomena, and mental processes such as thoughts, feelings, and motives. Psychology is an academic discipline of immense scope, crossing the boundaries between the natural and social ...
In psychoanalysis, resistance is the individual's efforts to prevent repressed drives, feelings or thoughts from being integrated into conscious awareness. [1]Sigmund Freud, the founder of psychoanalytic theory, developed the concept of resistance as he worked with patients who suddenly developed uncooperative behaviors during the analytic session.
If U = 0, T is said to be a completely non-unitary contraction. A special case of this decomposition is the Wold decomposition for an isometry , where Γ is a proper isometry. Contractions on Hilbert spaces can be viewed as the operator analogs of cos θ and are called operator angles in some contexts.
A definition of a function, set, or other mathematical object that is defined in terms of itself, using a base case and a rule for generating subsequent elements. recursive function A function that can be computed by a procedure that calls itself, directly or indirectly, with a base case to prevent infinite recursion.
