Economic-mathematical modeling of the functioning of the region in emergency situations

Natural and technological disasters are the reasons of imbalances appearing in different areas of the state which lead to inefficiency in economy. The economic-mathematical modeling describing these processes, allows optimizing the assessment of their impact

Pseudoclassical theories of Majorana, Weyl and Majorana--Weyl particles

A pseudoclassical theories of Majorana, Weyl and Majorana--Weyl particles in the space--time dimensions $D=2n$ are constructed. The canonical quantization of these theories is carried out and as a result we obtain the quantum mechanical description of neutral particle in $D=2n$ , Weyl particle in $D=2n$ and neutral Weyl particle in $D=4n+2$. In $D=2,4({\rm mod}8)$ dimensional space--time the description of the neutral particle coincides with the field theoretical description of the Majorana particle in the Foldy--Wouthuysen representation. In $D=8k+2$ dimensions the neutral Weyl particle coincides with the Majorana--Weyl particle in the Foldy--Wouthuysen representation.Comment: LATEX, 17 pages, no figure
