Lisa Lorentzen (also published as Lisa Jacobsen) is a Norwegian mathematician known for her work on continued fractions. She is a professor emerita in the Department of Mathematical Sciences at the Norwegian University of Science and Technology (NTNU). Books With , Lorentzen is the author of the book ''Continued Fractions with Applications'' (Studies in Computational Mathematics 3, North-Holland, 1992; 2nd ed., Atlantis Studies in Mathematics for Engineering and Science, Springer, 2008). She is also the author of two textbooks in Norwegian: ''Kalkulus for ingeniører'' [Calculus for engineers] and ' [What is mathematics?], and co-author with Arne Hole and Tom Louis Lindstrøm of ''Kalkulus med én og flere variable'' [Calculus with single and multiple variables].

Continued Fraction
In mathematics, a continued fraction is an expression (mathematics), expression obtained through an iterative process of representing a number as the sum of its integer part and the multiplicative inverse, reciprocal of another number, then writing this other number as the sum of its integer part and another reciprocal, and so on. In a finite continued fraction (or terminated continued fraction), the iteration/recursion is terminated after finitely many steps by using an integer in lieu of another continued fraction. In contrast, an infinite continued fraction is an infinite expression (mathematics), infinite expression. In either case, all integers in the sequence, other than the first, must be positive number, positive. The integers a_i are called the coefficients or terms of the continued fraction. It is generally assumed that the numerator of all of the fractions is 1. If arbitrary values and/or function (mathematics), functions are used in place of one or more of the numerat ...
