Compressed sensing for real measurements of quaternion signals
Agnieszka Badenska, Łukasz Błaszczyk
The article concerns compressed sensing methods in the quaternion algebra. We prove that it is possible to uniquely reconstruct - by norm minimization - a sparse quaternio…

Misiurewicz parameters for Weierstrass elliptic functions based on triangle and square lattices
Agnieszka Badenska
For two families of Weierstrass elliptic functions - based on triangular or square lattices - we prove that the set of Misiurewicz parameters has the Lebesgue measure zero in C.

No entire function with real multipliers in class S
Agnieszka Badenska
We prove that there is no entire transcendental function in class S with real multipliers of all repelling periodic orbits.
