I R TERRY, D A W GRAN , AND .1 111ERMONTAY L.OR (Depaoritnew of0 KSurgeriv, St Geotrge's Hospitall, Lon1doni) Appropriate intraperitoncal antiproteinase chemotherapy for ANP may include the use of oligopeptide inhibitors of bacterial origin as these agents are capable of inactivating pancreatic proteinases of different specificities in compilex with (xL-maicroglobulin.' We h.lve studied the eft...

A generalization of the GNS-representation is investigated that represents partial ∗-algebras as systems of operators acting on a partial inner product space (PIP -space). It is based on possibly indefinite B-weights which are closely related to the positive B-weights introduced by J.-P. Antoine, Y. Soulet and C. Trapani. Some additional assumptions had to be made in order to guarantee the GNS-...

Notice of formal retraction of article by Dr Y. Fujii. This article is being retracted as a result of: (1) Overwhelming evidence of fabrication, related to the fact that the distributions of many variables reported by Dr Fujii in these studies could not have occurred by chance; 2 and (2) The inability of Dr Fujii’s institutions to attest to the integrity of the study and/or its data conducted u...

It is known that there are exactly five positive universal products. We classify non-positive universal products and find a two-parameter deformation of the Boolean product, which we call (r, s)-products. Furthermore, we introduce a GNS-construction for non-positive linear functionals on algebras and study the GNS-modules of (r, s)-product functionals.
