We define weighted geometric mean method of convergence for sequences in R+ by using multiplicative calculus and obtain necessary and sufficient conditions under which convergence of sequences in R+ follows from convergence of their weighted geometric means. We also obtain multiplicative analogues of Schmidt type slow oscillation condition and Land...

In this paper, by using q -calculus (Jackson’s q -derivative) $$D_{q,p}$$ D q , p we defined new operator $$D_{\lambda ,q,p}^{n}f^{(m)}(z)$$ D λ , q , p n f ( m ) ( z ) . After that, we used this operator to introduce two new subclasses of multivalent analytic functions with complex order. Also, we obtained coefficients estimates and consequent inc...

We propose a calculus of string diagrams to reason about satisfiability of Boolean formulas, and prove it to be sound and complete. We then showcase our calculus in a few case studies. First, we consider SAT-solving. Second, we consider Horn clauses, which leads us to a new decision method for propositional logic programs equivalence under Herbrand...

One shortcoming of the chain rule is that it does not iterate: it gives the derivative of f(g(x)), but not (directly) the second or higher-order derivatives.
