The quantum Dirac-like equation and the QED vertex operator for a composite particle are suggested. The vertex operator and the fermionic propagator are connected by the QED Ward identity. It is shown that all of the Feynman QED-integrals for a three-component particle are finite with some suggestion about large momentum dependence of the vertex operator. This dependence is in agreement with the component counting rules.
The concept of the quantized space-time of the formless finite fundamental elements is suggested. This space-time can be defined as a set of continual space-time coverings by simply connected non-overlapping regions of any form and arbitrary sizes with some probability measure. The functional integrating method and the space-time action problem are analyzed. A string in this space-time is considered as an excitation of a number of fundamental elements forming one-dimensional curve. It is possible to direct the way for the volume term of the space-time action to yield the Nambu-Goto action with this consideration.
