Pseudomathematics, or mathematical crankery, is a mathematics-like activity that does not adhere to the framework of rigor of formal mathematical practice. Common areas of pseudomathematics are solutions of problems proved to be unsolvable or recognized as extremely hard by experts, as well as attempts to apply mathematics to non-quantifiable ...
In mathematics, pseudoanalytic functions are functions introduced by Lipman Bers (1950, 1951, 1953, 1956) that generalize analytic functions and satisfy a weakened form of the Cauchy–Riemann equations.

A field K is pseudo algebraically closed (usually abbreviated by PAC [2]) if one of the following equivalent conditions holds: Each absolutely irreducible variety V {\displaystyle V} defined over K {\displaystyle K} has a K {\displaystyle K} - rational point .
In mathematics, a pseudometric space is a generalization of a metric space in which the distance between two distinct points can be zero. Pseudometric spaces were introduced by Đuro Kurepa [1] [2] in 1934.

Suppose that k is a non-perfect field of characteristic 2, and a is an element of k that is not a square. Let G be the group of nonzero elements x + y √ a in k[√ a].There is a morphism from G to the multiplicative group G m taking x + y √ a to its norm x 2 – ay 2, and the kernel is the subgroup of elements of norm 1.
