12. Mai 2024 · The Theorem of Stone-Weierstraß tells us that the polynomials are uniformly dense in the continuous functions on a compact interval. So my first question ...
10. Mai 2024 · Searching for linear structures in the failure of the Stone-Weierstrass theorem. We analyze the existence of vector spaces of large dimension inside the set C ( L, \K) ∖ A ¯, where L is a compact Hausdorff space and A is a self-adjoint subalgebra of C ( L, \K) that vanishes nowhere on L and does not necessarily separate the points of L.
23. Mai 2024 · Introduction. A formal power series can be loosely thought of as an object that is like a polynomial, but with infinitely many terms.Alternatively, for those familiar with power series (or Taylor series), one may think of a formal power series as a power series in which we ignore questions of convergence by not assuming that the variable X denotes any numerical value (not even an unknown value).
Vor 5 Tagen · A Fourier series is a continuous, periodic function created by a summation of harmonically related sinusoidal functions. It has several different, but equivalent, forms, shown here as partial sums. But in theory The subscripted symbols, called coefficients, and the period, determine the function as follows: Fig 1.

Vor 3 Tagen · Location Weierstraß-Institut, Mohrenstr. 39, 10117 Berlin, Erdgeschoss, Erhard-Schmidt-Hörsaal Abstract Random Fields with posses the Markov Property have played an important role in the development of Constructive Field Theory. They are related to their relativistic counterparts through Nelson Reconstruction. In this talk I will describe an attempt to understand the Markov Property of the Φ
Vor 4 Tagen · This approach was generalized by Karl Weierstrass to what is now known as the Lindemann–Weierstrass theorem. That π is transcendental implies that geometric constructions involving compass and straightedge cannot produce certain results, for example squaring the circle.
