چکیده

Otto Mangold [5] was an early-twentieth-century embryologist who specialized in the development of amphibian embryos. A major emphasis of his research was refining the concept of the organizer [6], now referred to as embryonic induction [7]. He was born on 4 November 1891 in Auenstein, Germany, and came from what Viktor Hamburger [8], a colleague and personal acquaintance, described as ?peasant stock.? Mangold attended several universities including Tübingen, Freiburg, and Rostock. He was one of Hans Spemann?s first students at Rostock but had to leave to serve in the air force in World War I [9] .

Convergence of the Weierstrass Method for Simultaneous Approximation of Polynomial Zeros

In 1891, Weierstrass presented his famous iterative method for finding all the zeros of a polynomial simultaneously. In this paper we establish three new local convergence theorems for the Weierstrass method with a posteriori and a priori error estimates. The main result of the paper generalizes, improves and complements some well known results of Dochev (1962), Kjurkchiev and Markov (1983) and...
