The Ucisted cubics of the type 2 of constant torsion are of constant curvature, and formelsammlubg those of constant curvature are of con- stant torsion; they are all imaginary gelichstrommaschine satisfy the conditions 4. This type is even more general than that treated by Dr.

The invariants referred to in Professor Shaw’s paper are the scalar invariants which appear in the characteristic equa- tion, the expressions previously called chi, and related forms. On November 2,the Norwegian mathematical society was founded at Christiania. Neu bearbeitet von G. Then t and t’ are separated gleicshtrommaschine by o and o’; this follows immediately from the definition of a conjugate system.

The linear dependence of functions of several variables and certain completely integrable systems of partial differential equations. His touch was delicate and his musical intuition fine.

Wie kann ich formelsammlunb. Nevertheless, this work is expensive, so in order to keep providing this resource, we have taken steps to prevent abuse by commercial parties, including placing technical restrictions on automated querying. In general the second one-parameter family introduced in this way is entirely independent of the first family, and one might say that the properties of the first family are those properties of the net which remain unaltered if the second one-parameter family is changed in all possible ways.

Lastly I will add here a theorem on twisted cubics of constant torsion and of constant curvature. While at Columbia, Green became a member of Edward Kasner’s seminar. The subject is far too vast to gleichstfommaschine treated exhaustively in a thesis of twenty-seven pages; but the fundamentkl aspects of the theory are there developed and further work in this important field must inevitably set in where Green left off or else duplicate his work.

Gronwall has been appointed mathematics and dynamics expert on the technical staff of the ordnance oflSce, U. Kostka, of Insterburg, Dr. Roy has been appointed professor of analytical mechanics at the University of Toulouse, as successor to the late Professor S. Elements of plane trigonometry, with complete tables. New York, Macmillan, It appears therefore that Einstein’s assumption of differ- entiability is unnecessary, and that the needed features of ” homogeneity ” are already implicit in the optical and kinematic postulates as here interpreted.

This permits of a certain simplifica- tion of the conditions of the theorem, and a great simpli- fication in the demonstration. He was entirely self taught and was much hampered, in his earlier years, by the inadequacy of the piano which belonged to his parents.

In view of the general remark in the first paragraph it is clear that stronger thouch less simply stated theorems mav be obtained from identity 2. The first of several papers thereon was read at the first meeting of the American Association for the Advancement of Science in Ausgabe B Progymnasien imd Realschulen: Public domain books are our gateways to the past, representing a wealth of history, culture and knowledge that’s often difficult to discover.

Hat Jemand genauere Infos und macht vielleicht das selbe? Hale, partly as a preparedness measure, with the realization that in case of war cooperation would be imperative for efficient service from our scientific men. By availing himself of the full force of a new proof of Muir’s recent theorem Messenger of Mathematics, May, that ” a determinant can be expressed in terms of minors drawn from four mutually exclusive arrays, two of which are coaxial and complementary to one another,” Mr.


In Professor Bliss’s first paper the properties of these functions of functions are discussed. Reed, of the Uni- versity of Illinois, Dr.

Maddox has been appointed assistant professor of mathematics at the Oklahoma Agricultural and Mechanical College. The present edition of Cajori’s well known History of Mathematics is so completely revised and so considerably en- larged that it might almost be regarded as a new book. For the present purpose it will be assumed that in every system the corresponding scheme of measure- ment is of the kind described. The field to be covered is so extensive and the number of data is so large that it is almost impossible to avoid entirely the appearance of some misleading statements.

C, during the past year, was recently made a member of the General Staff. By simple vector considerations Professor Kempner detennines certain sectors starting at the origin in the complex plane which do not contain roots of a given algebraic equation. But this does not seem to be the meaning of the authors.

On the linear dependence of functions of one variable. The following thirty-three papers were read: About a year before our entry into the war the National Research Council was organ- ized under the enthusiastic and capable leadership of Dr.
