Homotopy Colimits of Algebras Over Cat-Operads and Iterated Loop Spaces
Zbigniew Fiedorowicz, Manfred Stelzer, Rainer M. Vogt
We extend Thomason's homotopy colimit construction in the category of permutative categories to categories of algebras over an arbitrary $\Cat$ operad and analyze its properties. W…

Shearlets and Optimally Sparse Approximations
Gitta Kutyniok, Jakob Lemvig, Wang-Q Lim
Multivariate functions are typically governed by anisotropic features such as edges in images or shock fronts in solutions of transport-dominated equations. One major goal both for…

An Additivity Theorem for the Interchange of E_n Structures
Zbigniew Fiedorowicz, Rainer M. Vogt
The notion of interchange of two multiplicative structures on a topological space is encoded by the tensor product of the two operads parametrizing these structures. Intuitively on…
