Gian Francesco Malfatti (1731-1807) geometer The famous Malfatti problem, to construct in a triangle three circles, each tangent to the other two and to two sides of the triangle, was first solved analytically by Malfatti in 1802. Because of their close connection to the Malfatti problem, certain recently discovered triangle centers are now known as the Ajima-Malfatti points and the Yff-Malfatti point After completing his studies in Bologna, Malfatti founded a school of mathematics and physics at Ferrara in 1754. He became professor of mathematics at the re-established University of Ferrera in 1771. Two-hundred twenty-seven years later, Professor Luigi Pepe of the same mathematics department kindly contributed the likeness of Malfatti which you see here.

YFF-MALFATTI POINT The Malfatti problem, dating from Ajima in the late 1700's and Malfatti in the early 1800's, is to construct three circles inside a triangle, each tangent to the other two and also tangent to two of the sidelines of the triangle. In 1997, Peter Yff considered the classical Ajima-Malfatti configuration and realized that if the requirement that the circles lie inside the triangle is dropped, then there is a second configuration that solves the problem. Moreover, in analogy with the classical Ajima-Malfatti configuration, there is an interesting triangle center. In the figure, the reference triangle is labeled ABC, and the points of pairwise tangency of the circles are labeled A', B', C'. The lines AA', BB', CC' concur in the Yff-Malfatti point, labeled YM. Trilinear coordinates for the Yff-Malfatti point are [csc(A/4)]^4 : [csc(B/4)]^4 : [csc(C/4)]^4.

Malfatti circles From Wikipedia, the free encyclopedia. Construct three circles inside a given triangle such that each circle is tangent to the other two and to two sides of the triangle. edit History In Gian Francesco Malfatti thought that solving this problem would also provide a solution to Malfatti's problem . However in , it was shown that the Malfatti circles were not always the best solution. Then in Goldberg showed that, even worse, they are never the best solution ( Ogilvy ). Ogilvy ( ) and Wells ( ) then illustrated specific cases where alternative solutions are clearly optimal. edit External links Mathworld Malfatti Circles Mathworld Malfatti's Problem Malfatti's Problem (From Interactive Mathematics Miscellany and Puzzles.

Then, in 1754, Malfatti went to Ferrara where he taught mathematics and physics in a school that he started up there. University of Ferrara was erected by Alberto V who reigned over Ferrara from 1388 to 93. The University was obtained by Pope Boniface IX as a concession in 1391 and this is taken as its founding date. Copernicus studied there in 1503 but the buildings which house the University today date from the end of the 16 th -century. The University of Ferrara was re-established in its 16 th -century buildings in 1771 and Malfatti was appointed to the chair of mathematics there in that year. Struik , describing the papers in [2], writes that Malfatti:- ... was a quiet, scholarly man who spent most of his life as a librarian and professor in Ferrara. He was one of the founders of the "Societa Italiana delle Scienze"
