n The Federalist, James Madison wrote that in fashioning the federal relationship "the convention must have been compelled to sacrifice theoretical propriety to the force of extraneous circumstances." These sacrifices which produced a "compound republic, partaking both of the national and federal character" were "rendered indispensable" by what Madison termed "the peculiarity of our political s...

Let R be a commutative ring. Unless indicated otherwise, all modules are R-modules and all tensor products are taken over R, so we abbreviate ⊗R to ⊗. A bilinear function out of M1 × M2 turns into a linear function out of the tensor product M1 ⊗ M2. In a similar way, a multilinear function out of M1 × · · · ×Mk turns into a linear function out of the k-fold tensor product M1 ⊗ · · · ⊗Mk. We wil...

The Unitary Executive offers a powerful case for the historical pedigree of the unitary executive theory. Offering an account of presidential practice stemming from George Washington to George W. Bush, the book seeks to ground unitary executive theory with exhaustive historical evidence. Although the authors do not purport to present a history of the presidency, they do provide important and co...

Scientists working in areas that are (rightly or wrongly) socially contentious might benefit by perusing readers' comments lodged on online newspaper websites after the appearance of announcements in their fields. On many occasions, they would find not only approving sentiments but also a surprising degree of hostility. The recent announcement of draft sequence coverage of the wheat genome prov...

The present Article is an attempt to analyze the scheme of Separation of Powers as envisaged under the Indian Constitution and the difficulties faced by the three wings of the government in practice while implementing the provisions of the Constitution in letter and spirit. The author also draws a comparative analysis with the American Constitution scheme of Separation of Powers. Throughout the...

This work is devoted to proving that, given an integer $x \ge 2$, there are infinitely many perfect powers, coprime with $x$, having exactly $k 3$ non-zero digits in their base $x$ representation, except for the case $x=2, k=4$, which a known finiteness result by Corvaja and Zannier holds.

The natural notion of categoricity, as it was discovered in the 1930's, is degenerate for first order languages, since only a finite structure can be described up to isomorphism by its first order theory. This has led to a new notion of categoricity. A theory is said to be categorical in a power if it has a model of this power which is unique up to isomorphism. Morley has proved, answering the ...
