Let $ \gamma$ be a limit ordinal with cofinality $ \kappa > \omega$ . Is there a stationary subset of $ \gamma$ (a subset of $ \gamma$ that meets every closed unbounded subset of $ \gamma$ ) of size $ \kappa$ ?Read more

This morning I wrote with the help of a CAS, and integral representation for the ApĂ©ry’s constant $ \zeta(3)$ and some standard formulas two formulas involving this constant. I would like to know if these were in the litetature (my purpose is to know if if it possible to justify these and/or exploit to getRead more
I wanted to install the gamma package described here (www.gran.name). The package seems to have installed correctly. However, I am not seeing any symbolic output. The outputs should be like these described here (http://xxx.lanl.gov/pdf/hep-th/0105086v2). But I am getting these. Any idea how to solve this?Read more
Is the value of the following series known? $ $ \sum_{k=0}^\infty \frac{\Gamma(a+k) \Gamma(b+k)}{\Gamma(a+b+k+1) k!}$ $ ……… If it is known kindly give a reference. It arises through some problem.Read more
Is the matrix \sigma_{\mu\nu} = \frac{i}{2} [\gamma_\mu, \gamma_\nu] defined in FeynCalc? I know that $ \gamma_\mu$ is Ga[mu].Read more
