    One of the most studied SPDEs is the stochastic heat equation,which may formally be written as 1. ∂ t u = Δ u + ξ , {\displaystyle \partial _{t}u=\Delta u+\xi \;,} where Δ {\displaystyle \Delta } is the Laplacian and ξ {\displaystyle \xi } denotes space-time white noise. Other examples also include stochastic versions of famous linear equations, su...

    One difficulty is their lack of regularity. In one dimensional space, solutions to the stochastic heat equation are only almost 1/2-Hölder continuous in space and 1/4-Hölder continuous in time. For dimensions two and higher, solutions are not even function-valued, but can be made sense of as random distributions. For linear equations, one can usual...

  5. e. In cosmology, the cosmological constant (usually denoted by the Greek capital letter lambda: Λ ), alternatively called Einstein's cosmological constant, is the constant coefficient of a term that Albert Einstein temporarily added to his field equations of general relativity. He later removed it, however much later it was revived and ...

    World War II [b] or the Second World War (1 September 1939 – 2 September 1945) was a global conflict between two major alliances: the Allies and the Axis powers. The vast majority of the world's countries, including all the great powers, fought as part of these military alliances.
