He died on January 24,at Cam- bridge, Massachusetts.

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. There is a very noticeable lack of uniformity as regards names.

View 8 more comments. Hussey at the Detroit Observatory on Tuesday evening, and auto rides around Ann Arbor and to the neighbor- ing city of Detroit were only three of the many kindnesses of the hosts. The subject is intimately connected with the Fredholm theory in integral equations.

For passing from representations to compositions, the foUowing 13 useful: The Ucisted cubics of the type 2 of constant torsion are of constant curvature, and conversely those of constant curvature are of con- stant torsion; they are all imaginary and satisfy the conditions 4.

On page of Merriman and Woodward’s Higher Mathematics is given a table showing — for different values of the interpolating factor — the actual and the theoretical average errors of certain interpolated values. Beal, of the University of Tennessee, has been appointed assistant professor of mathematics at the University of Pennsylvania. A summary of my theory of the sun. It will be published in the Journal of the U. In Enneper’s Elliptische Functionen, page 27, may be found a method due to Weierstrass of reducing the general elliptic element to the Weierstrass form.

GLEICHSTROMMASCHINE – Definition and synonyms of Gleichstrommaschine in the German dictionary

In the following sec: A similar theorem for uniform convergence may be form- ulated in an obvious manner. Nevertheless, diligent practice on this instrimient and a dumb keyboard enabled him to acquire an extensive repertoire and a remarkable technique. It may be stated as follows: It is frequently very undesirable to give only the family name since the number of family names represented by different mathematicians is already large and is constantly growing larger. At the University of Pennsylvania, Dr.

Meaning of “Gleichstrommaschine” in the German dictionary

After our entry into the war innumerable problems of a scientific character were presented to the Council and through its aid were effectively treated.

The present work appears to be satisfactory along these important lines, as might have been expected from the fact that its author has had such a broad training in writing on the history of mathematics. I was led to a consideration of identity 1 in connection with the problem of integration of a Stieltjes integral by parts. The computation of the values corresponding to the other ages is eliminated by the method and an enormous saving of labor is thus gained.

In Professor Bliss’s first paper the properties of these functions of functions are discussed. 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. New York, Heath, The factor of proportionality, the velocity of light, is assumed to be the same for all pairs of points, in any single system, and for convenience is taken as having the same numerical value c in every system by means of a single admissible restriction on the units of length and time in each.

Lane studies the properties of the joint-axis congruence, and of the suite of Laplace transforms of Sy, which are charac- teristic of this configuration when the developables of the joint-axis congruence are indeterminate. Theory of sets of points; func- tions of a real variable and their integrals; theorems of existence for ordinary differential equations, three hours.


The results obtained are special cases of those of the preceding paper, but they are here deduced independently except for some general theorems which would very likely be accepted by an applied mathematician as intuitively true.
