What are Janos Bolyai\'s important details in regards to his work on non-Euclidean geometry?

Solution

Solution -

There is evidence to suggest that he had developed most of what would appear in his treatise as a complete system of non-Euclidean geometry. In early 1825 Bolyai travelled to Marosvásárhely and explained his discoveries to his father. In addition to his work on geometry, Bolyai developed a rigorous geometric concept of complex numbers as ordered pairs of real numbers. He never published more than the few pages of the Appendix he left more than 20000 pages of manuscript of mathematical work when he died.
