Abstract

A simple model for the calculation of configurational and rheological properties of finitely extensible polymers in flow is introduced. The finite extensibility of the chain is incorporated into the common Rouse model by varying the spring constant such that a constant contour length is maintained for every flow strength. For elongational flow, a comparison with Monte Carlo simulations of a bead‐rod chain with 100 links yields qualitative agreement. For shear flow, this model predicts non‐Newtonian flow behaviour.

## Abstract When the stress applied to a Rouse‐like polymer chain is large enough, one must use anharmonic entropic spring forces in order to keep the chain contour length from increasing to unphysical values. Although one can derive β€œexact” equations relating the spring extension to the entropic f

This paper describes generic patterns for the extensions between simple modules of a finite Chevalley group. A one-to-one correspondence between these extensions and the extensions between certain simple modules of the ambient algebraic group are established. It is shown that an extension appears in

## Abstract It is proved that the variety of relevant disjunction lattices has the finite embeddability property. It follows that Avron's relevance logic **RMI**~min~ has a strong form of the finite model property, so it has a solvable deducibility problem. This strengthens Avron's result that **RM
