We have two polynomial time results for the uniform word problem for a quasivariety Q: (a) The uniform word problem for Q can be solved in polynomial time iff one can find a certain congruence on finite partial algebras in polynomial time. (b) Let Q* be the relational class determined by Q. If any universal Horn class between the universal closure S(Q*) and… (More)

Combinatorial classes T that are recursively defined using combinations of the standard multiset, sequence, directed cycle and cycle constructions, and their restrictions, have generating series T(z) with a positive radius of convergence; for most of these a simple test can be used to quickly show that the form of the asymptotics is the same as that for the… (More)

Access to dental care is an essential need for all patients, particularly for individuals with complex medical conditions. Consequently, dentists have a moral and professional obligation to provide care for all individuals within the dentist's realm of expertise. However, throughout the HIV epidemic dental professionals have demonstrated an unwillingness to… (More)

We determine precisely those locally finite varieties of unary algebras of finite type which, when augmented by a ternary discriminator, generate a variety with a decidable theory.

This paper surveys and updates results and open problems related to the variety defined by the High School Identities as well as the variety generated by the positive numbers with exponentiation. The set of eleven basic identities of the positive integers N with the operations +,×, ↑ which one learns in high school are as follows (the subset not involving… (More)

Exponentiating a power series can have the effect of smoothing out the behavior of the coefficients. In this paper we look at conditions on the growth of the coefficients of G(x) = ∑ g(n)x, where g(n) ≥ 0, which ensure that f(n−1)/f(n)→ ∞, where F(x) = e. Useful notation will be f(n) ≺ g(n) for f(n) eventually less than g(n) and f(n) ∈ RT∞ for f(n− 1)/f(n)… (More)
