An N=1 supersymmetric system is constructed and its integrability is shown by obtaining three soliton solutions for it using the supersymmetric version of Hirota's direct method.Comment: 10 pages, no figure

Strategic Analysis on the Public Power INfluence

Competitors, clients, suppliers, potential competitors, substitute products. All represent competitive forces, considered as being representative for characterising the competition relationships in all industries. In reality however, within the market competition game, a new „economic organisation” interferes- the state. It can directly or indirectly influence various aspects related to the structure of one specific field. The state can either be client (for defence sector products) or supplier (of raw materials controlled exclusively by the state) in many sectors or can influence the structural evolution of a certain activity field by regulating key variables such as: sector entrance, concurential practices, profitability. Regulations regarding products` quality and security, environment`s quality, custom rights or facilities offered to different investors` categories are less direct instruments public power uses to influence relationships in a concurential environment. The present paper focuses on the main modalities and forms of intervention through which the state currently prevails as a major concurential player.state, competitive environment, intervention, price control, international competition.
