We prove space-time parabolic Besov regularity in terms
of integrability of Besov norms in the space variable for solutions of the
heat equation on cylindrical regions based on Lipschitz domains.

The class of NPc-lattices is introduced as a quasivariety of commutative residuated lattices, and it is shown that the class of pairs $(\A, A^+)$ such that $\A$ is an NPc-lattice and $A^+$ is its positive cone, is a matrix semantics…

In this note we give sufficient conditions on two dyadic systems on a space of homogeneous type in order to obtain the equivalence of corresponding Haar systems on Lebesgue spaces. The main tool is the vector valued Fefferman-Stein inequality for…

Spinks and Veroff have shown that constructive logic with strong negation (CLSN for short), can be considered as a substructural logic. We use algebraic tools developed to study substructural logics to investigate some axiomatic extensions of CLSN. For instance we…

A standard engineering procedure for approximating the solutions of an infinite-dimensional inverse problem of the form Ax = y, where A is a given compact linear operator on a Hilbert space X and y is the given data, is to…
