✦ Synopsis

This paper proposes a method for the representation of functions describing a measured geophysical property (via sparsely scattered ordensely defined point data) by tensor and triple product interval B-splines (IBS). The spline representation facilitates archiving, data storage reduction, visualization and more general highlevel interrogation. Interval methods allow for the representation of the function values together with their uncertainty. The uncertainty is introduced, for example, because the measurement (or dependent variable) or the location of the sensor (the independent variable@)) is known only to a finite precision. In this paper, we present algorithms for the creation of IBS geometries based on minimization with linear constraints and we illustrate the method using geophysical ocean data and their interrogation.

## Abstract We consider some initial–boundary value problems for non‐linear equations of thermoviscoelasticity in the three‐dimensional case. Since, we are interested to prove global existence we consider spherically symmetric problem. We examine the Neumann conditions for the temperature and eithe

## Abstract A local energy decay problem is studied to a typical linear wave equation in an exterior domain. For this purpose, we do not assume any compactness of the support on the initial data. This generalizes a previous famous result due to Morawetz (__Comm. Pure Appl. Math__. 1961; **14**:561–
