Second order ordinary differential equations that possesses the constant invariant are investigated. Four basic types of these equations were found. For every type the complete list of nonequivalent e...
We exhibit an encoding of knots into processes in the -calculus such that knots are ambient isotopic if and only their encodings are weakly bisimilar.
Radical Anti-Invariant Lightlike Submanifolds of Semi-Riemannian Product Manifolds

We introduce radical anti-invariant lightlike submanifolds of a semi Riemannian product manifold and give examples. After we obtain the conditions of integrability of distributions which are involved ...
