A Variety with Solvable, but Not Uniformly Solvable, Word Problem

In the literature two notions of the word problem for a variety occur. A variety has a decidable word problem if every finitely presented algebra in the variety has a decidable word problem. It has a uniformly decidable word problem if there is an algorithm which given a finite presentation produces an algorithm for solving the word problem of the algebra so presented. A variety is given with f...

Infinitely Many Quadratic Diophantine Equations Solvable Everywhere Locally, But Not Solvable Globally∗

We present an infinite class of integers 2c, which turn out to be Richaud-Degert type radicands, for which 2x2 − cy2 = −1 has no integer solutions, but for which 2x2 − cy2 ≡ −1 (mod n) has integer solutions for any n ∈ N. This explains a topic often seen in introductory number theory courses, that appears as a curiosity, yet for which we are able to give the underlying reasons in terms of simpl...

Multidrug resistance: a solvable problem?

The results of chemotherapy of pancreatic cancer have been disappointing thusfar. Pancreatic tumors are primary resistant to available drugs. Why that is, is as hard to define as why normal tissues are resistant. Meaningful studies on drug resistance of pancreatic tumors can only be expected after a highly effective drug has been found. While waiting for this magic bullet to arrive, I shall rev...
