The aim of this note is to improve and complete the estimates given in our paper, Arch. Ration. Mech. Anal. 82, 13-25 (1983). We deal with the problem as introduced by M. E. Gurtin and R. C. MacCamy, ibid. 54, 281-300 (1974), that is to say, we are looking for a function ρ(a,t) satisfying:

ρ a (a,t)+ρ t (a,t)+μ(a,t,P(t))ρ(a,t)=0 for a,t>0,

ρ (0,t)=∫ 0 +∞ β(a,t,P(t))ρ(a,t)da, t>0, ρ(a,0)=φ(a), a>0, where P(t)=∫ 0 +∞ ρ(a,t)da.

## Abstract

The aim of this note is to improve and complete the estimates given in our paper, Arch. Ration. Mech. Anal. 82, 13-25 (1983). We deal with the problem as introduced by M. E. Gurtin and R. C. MacCamy, ibid. 54, 281-300 (1974), that is to say, we are looking for a function ρ(a,t) satisfying:

ρ a (a,t)+ρ t (a,t)+μ(a,t,P(t))ρ(a,t)=0 for a,t>0,

ρ (0,t)=∫ 0 +∞ β(a,t,P(t))ρ(a,t)da, t>0, ρ(a,0)=φ(a), a>0, where P(t)=∫ 0 +∞ ρ(a,t)da.

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.

You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
