Stanisław Łojasiewicz (9 October 1926 – 14 November 2002) was a Polish mathematician.

Biography
At the end of the 1950s, he solved the
problem of distribution division by
analytic function
In mathematics, an analytic function is a function that is locally given by a convergent power series. There exist both real analytic functions and complex analytic functions. Functions of each type are infinitely differentiable, but complex ...
s, introducing the
%C5%81ojasiewicz inequality. Its solution opened the road to important results in the new theory of
partial differential equations
In mathematics, a partial differential equation (PDE) is an equation which imposes relations between the various partial derivatives of a multivariable function.
The function is often thought of as an "unknown" to be solved for, similarly to ...
. The method established by
Łojasiewicz led him to advance the theory of
semianalytic set In mathematics, particularly in the subfield of real analytic geometry, a subanalytic set is a set of points (for example in Euclidean space) defined in a way broader than for semianalytic sets (roughly speaking, those satisfying conditions requirin ...
s, which opened an important chapter in modern analysis.
Commemoration
The ''Łojasiewicz Lectures''
are a series of annual lectures in
mathematics given at the
Jagiellonian University in honour of Łojasiewicz.
