## Commentationes Arithmeticae

Following the tradition of the American Mathematical Society, the seventh colloquium of the Society was held as part of the summer meeting that took place at the University of Wisconsin, in Madison. Two sets of lectures were presented: On Invariants and the Theory of Numbers, by L. E. Dickson, and Functions of Several Complex Variables, by W. F. Osgood. Dickson considers invariants of quadratic forms, with a special emphasis on invariants of forms defined in characteristic $p$, also called modular invariants, which have number-theoretic consequences. He is able to find a fundamental set of invariants for both settings. For binary forms, Dickson introduces semi-invariants in the modular case, and again finds a fundamental set.These studies naturally lead to the important study of invariants of the standard action of the modular group. The lectures conclude with a study of 'modular geometry', which is now known as geometry over $\mathbf{F}_p$. The lectures by Osgood review the state of the art of several complex variables. At this time, the theory was entirely function-theoretic. Already, though, Osgood can introduce the ideas and theorems that will be fundamental to the subject for the rest of the century: Weierstrass preparation, periodic functions and theta functions, singularities - including Hartogs' phenomenon, the boundary of a domain of holomorphy, and so on.

## The Princeton Colloquium

Following the early tradition of the American Mathematical Society, the sixth colloquium of the Society was held as part of the summer meeting that took place at Princeton University. Two sets of lectures were presented: Fundamental Existence Theorems, by G. A. Bliss, and Geometric Aspects of Dynamics, by Edward Kasner. The goal of Bliss' Colloquium Lectures is an overview of contemporary existence theorems for solutions to ordinary or partial differential equations.The first part of the book, however, covers algebraic and analytic aspects of implicit functions. These become the primary tools for the existence theorems, as Bliss builds from the theories established by Cauchy and Picard. There are also applications to the calculus of variations. Kasner's lectures were concerned with the differential geometry of dynamics, especially kinetics. At the time of the colloquium, it was more common in kinematics to consider geometry of trajectories only in the absence of an external force. The lectures begin with a discussion of the possible trajectories in an arbitrary force field. Kasner then specializes to the study of conservative forces, including wave propagation and some curious optical phenomena. The discussion of constrained motions leads to the brachistochrone and tautochrone problems. Kasner concludes by looking at more complicated motions, such as trajectories in a resisting medium.

## The New Haven Colloquium

The American Mathematical Society held its fifth colloquium in connection with its thirteenth summer meeting, under the auspices of Yale University, during the week September 3-8, 1906. This book contains the lecture notes for the three courses that were given at this colloquium: 'Introduction to a Form of General Analysis' by Eliakim H. Moore, 'Projective Differential Geometry' by Ernest J. Wilczynski, and 'Selected Topics in the Theory of Boundary Value Problems of Differential Equations' by Max Mason.
