ABSTRACT: The present paper contains an explicit
rrpresentation of the
results announced by the author in Z_Ref 6,7 7- Chapter I %
A zero-dimensional, open mapping increasing the dimension is
representable as 1.) superposition of an irreducible mapping
and of a mapping not increasing the dimension 2.) sum of
finitely many twofold mappings and of mappings by which the
dimension is not increased (if the dimension of the original
is finite). Chapter II : Example of a zero-dimensional open
mapping of a one-dimensional continuum onto a square (see
A.H. Kolmogorov Z-Ref 1-7 and Ya.T,-,. Kazhdan Z_Ref 2_7).

ABSTRACT: The author presents a brief review of the status of re-
search in superconductivity, with special emphasis on practical ap-
plications and the difficulties brought about by the very low tem-
perature required and by the destruction of superconductivity in
relatively weak magnetic fields. He then rev3.ews the main ideas
advanced by W. A. Little (Superconductivity at Room Temperature,
Scientific American 212 (2), 21, 1965), where the posoibility of
synthesizing of organic materials capable of conducting electricit

without resistance is discussed. The objections to Little's
hypothe-
sis both from the point of view of the principles involved
and from
the point of view of the deductions, are reviewed,
particularly the
objection that Little's result contradicts the known theorem
that
a phase transition into an ordered state is impossible Ln a
one-
dimensional system such as the hypothetical superconducting
molecule
pr-)posed by Little. In view of this major objection, the
author
mentions the proposal made by Ginzburg and K_irzh.iits (ZhETF
v. 46,
397, 1964) for effecting surface superconductivity.

first considered by Gurevich, Larkin, and Pirsov (FTT 4,
1895, 1962),
and which is free of the main obsta~_-le to SUperconductivity
(Coulomb
repulsion of electrons), is also discussed in detail. It is
stated
in the conclusion that the possibility of obl-ain-in,, a
supr2rconductor
with sufficiently high critical temperature (at 1,2ast on the
Order
of 100K) is still the major obstacle to overcor-e in tiiis
research,

ABSTRACT: The present work calculates the probability of the
formation
of an electron-hole-pair in a strong electric field taking
into account the interaction of electrons with phonons. The
direct penetration of a valence electron into the conductive
zone and transition under participation of a phonon are in
first approximation independent of each other and can be in-,
vestigated separately. First, the initial conditions)as
well as an expression for the probability of penetration
during one period of oscillation are written down. The pre-
sence of rapidly oscillating factors under the integral sign
Card 1/4 of a formula given here leads to a very rapid decrease of

the probability of penetration with increasing maximum value.
The author then derives a formula for the number of else..
trons entering the conductive zone within one unit of volume
and one unit of time. The formula derived applies to lat-
tices of any symmetry,as well as to any directions of the
field. With rising temperature an exponential increase of
amperage begins, which is maintained up to values of T - T D
(T denoting the Debys' temperature). At T > T the number
n Pf pairs formed may depend weakly and linearly on
temperature.
At low temperatures n practically does not depend on the
temperature. The dependence of the critical field strength
an temperature is the most interesting from a practical point
of view. By critical field strength the author refers to
that field strength at which amperage reaches a certain pre-
given value. In the case of a compound lattice there are
always various types of phonons with the same wave vector Li-'
different frequencies (acoustic and optical frequencies).
The temperature dependence of the passage coefficient must
then apparently have the shape of a "steplike" curve. The
Card 2/4 range within which this dependence is of importance
can
