Category of $H$-groups
This paper develops a basic theory of $H$-groups. We introduce a special quotient of $H$-groups and extend some algebraic constructions of topological groups to the category of H-groups and H-maps and then present a functor from this category to the category of quasitopological groups.
متن کاملAssociated W±H∓ production at e+e− and hadron colliders
We show some results in the minimal supersymmetric Standard Model (MSSM) and the two Higgs doublet model (THDM) for WH production cross sections at ee and hadron colliders. 1 We demonstrate that the predictions for the cross sections in the two models can be vastly different. Observing these processes, once the existence of a charged Higgs is established, might shed some light on the underlying...
متن کاملT H E ANTIGENICITY OF d-RIBONUCLEASE; T H E INHIBITION OF T H E ENZYME BY ITS HOMOLOGOUS IMMUNE SERUM* BY J. SMOLENS AND M. G. SEVAG
A thermostable enzyme capable of digesting d-ribose (yeast) nucleic acid was first described by W. Jones in 1920 (1). A partial purification of this enzyme with acetone was carried out by Dubos and Thompson who called the enzyme ribonuclease (2). Kunitz described the preparation and properties of a crystalline protein he isolated from beef pancreas which appeared to be the same as the ribonucle...
متن کاملPREPARATION AND CHARACTERIZATION OF [Ni (MAP) ] ; H- MAP = 2- (METHYLAMINO) PYRIDINE H. Aghabozorg* and H. H. Monfared
We have recently synthesized [Ni (MAP) ] complex [H-MAP= 2- (methylamino) pyridine]. 2- (Methy1amino)pyridine reacts with MeLi in THF and generates the lithium salt (Li-MAP). Further reaction of NiCl with two equivalent of this ligand in THF leads to the formation of a dark red solution. Analytical data, molecular weight, and magnetic susceptibility of this complex confirm the formula [N...
متن کاملFlicker Response Contours for T H E Sparrow, and T H E Theory of the Avian Pecten by W. J. Crozier and Ernst Wolf
For image-forming animals generally it has been found that reduction of the light-time fraction in the light/dark cycle results in enlargement of the F-log I contour for response to flicker and in movement of the curve to lower flash intensities. 1 The asymptotic maximum of the curve is directly proportional to the percentage dark-time, and the abscissa of inflection (T') of the F-log I probabi...
