WebStrassen’s theorem circa 1965 gives necessary and sufficient conditions on the existence of a probability measure on two product spaces with given support and two marginals. In the … WebStrassen’s theorem asserts that a stochastic process is increasing in convex order if and only if there is a martingale with the same one-dimensional marginal distributions. Such …
WebIndeed, (1.5) can be used together with the Strassen theorem on marginals of probability measures (see Dudley [ 10, Theorem 1 I), an approximation theorem of Berkes and Philipp [2, Theorem 11, and a functional law of the iterated logarithm for Gaussian processes due to T.

It states that, for suitable fields, suitable formal power series with coefficients in the valuation ring of the field have only finitely many zeroes.
WebThe theorem is easily generalized to multivariate functions, replacing intervals with the more general concept of connected open sets, that is, domains, and the original function with some F(x) : Rn→ R, with the constraints of continuity and nullity of its integral over any subdomain D⊂ Ω. WebStrassen’s theorem (1965) is a fundamental theorem in the theory of stochastic dominance. It characterizes a stochastic dominance relationship between two random variables as an …

It is faster than the standard matrix multiplication algorithm for large matrices, with a better asymptotic complexity, although the naive algorithm is often better for smaller matrices. The Strassen algorithm is … See more Volker Strassen first published this algorithm in 1969 and thereby proved that the $${\displaystyle n^{3}}$$ general matrix multiplication algorithm was not optimal. The Strassen algorithm's publication resulted in more … See more Let $${\displaystyle A}$$, $${\displaystyle B}$$ be two square matrices over a ring $${\displaystyle {\mathcal {R}}}$$, for example matrices whose entries are integers or the real … See more The outline of the algorithm above showed that one can get away with just 7, instead of the traditional 8, matrix-matrix multiplications for the sub-blocks of the matrix.
