Danilo Blanuša (7 December 1903 – 8 August 1987) was a Croatian mathematician, physicist, engineer and a professor at the University of Zagreb.
Blanuša's most important works were related to isometric immersions of pseudo-Riemannian manifolds in differential geometry.
In particular, in his most cited work [2] he has exhibited an embedding of a hyperbolic (Lobachevsky) two-dimensional plane into 6-dimensional Euclidean space and another construction, for all natural numbers
Some of his results are included in the Japanese mathematical encyclopedia Sugaku jiten in Tokyo, published by Iwanami Shoten in 1962.
He discovered a mistake in relations for absolute heat Q and temperature T in relativistic phenomenological thermodynamics, published by Max Planck in Annalen der Physik in 1908.
This correction was published in Glasnik, the journal relating to mathematics, physics and astronomy in 1947 in the article "Sur les paradoxes de la notion d'énergie".
