Abstract. For a positive definite fundamental tensor all known examples of Osserman algebraic curvature tensors have a typical structure. They can be produced from a metric ...

MultipleLogListPlot is an elaborate overlay on MultipleListPlot that permits the user to enter data in linear coordinates and display the graph in LogLog, LogLinear, ...

In the last few weeks, SuDoKu has become very popular in Israel. Just for the fun of it, I made this notebook, in the very few hours of spate time I found. It is enjoyable to ...

Recent years have witnessed renewed developments of the rule-based programming style, addressing both its theoretical foundations and its practical implementations. New ...

We consider a special case of the Euler-Poisson system describing the motion of a rigid body with a fixed point. This is an autonomous sixth-order ODE system with one ...

In this paper, the new short-term problems that are faced by a generation company in a deregulated electricity market are addressed and an optimization algorithm is proposed. ...

In this paper we formalize a combinatorial object for describing link diagrams called a Planar Diagram Code (PD-Code). PD-codes are used by the KnotTheory Mathematica package ...

We use generalized unitarity at the integrand-level to directly construct local, manifestly dual-conformally invariant formulae for all two-loop scattering amplitudes in ...

This book contains materials from the course "Mathematical Analysis," taught in the first and second semesters at the Department of Economics of the Institute of Economics, ...
