Vector variational problem with knitting boundary conditions
G. Carita, V. Goncharov, G. Smirnov
We consider a variational problem with a polyconvex integrand and nonstandard boundary conditions that can be treated as minimization of the stress energy during the suturing proce…
Looking for granulation and periodicity imprints in the sunspot time series
Ilidio Lopes, Hugo G. Silva
The sunspot activity is the end result of the cyclic destruction and regeneration of magnetic fields by the dynamo action. We propose a new method to analyze the daily sunspot area…
Equivalence relations between the Cortie and Zurich sunspot group morphological classifications
V. M. S. Carrasco, L. Lefevre, J. M. Vaquero +1
Catalogues of sunspots have been available with useful information about sunspots or sunspot groups for approximately the last 150 years. However, the task of merging these catalog…
Andreev spectroscopy of Majorana states in topological superconductors with multipocket Fermi surfaces
Ana C. Silva, Miguel A. N. Araújo, Pedro D. Sacramento
The topological properties of a multiband topological superconductor in two dimensions are studied, when the latter is obtained by introducing electron pairing in an otherwise topo…
