Convergence and Optimization Results for a History-dependent Variational Problem
Mircea Sofonea, Andaluzia Matei
We consider a mixed variational problem in real Hilbert spaces, defined on on the unbounded interval of time and governed by a history-dependent operator. We state the unique solva…
Solvability and optimization for a class of mixed variational problems
Andaluzia Matei, Mircea Sofonea
We consider an abstract mixed variational problem governed by a nonlinear operator and a bifunctional , in a real reflexive Banach space . The operator is assumed to…
On the relationship between alternative variational formulations of a frictional contact model
Andaluzia Matei
We consider a frictional contact model, mathematically described by means of a nonlinear boundary value problem in terms of PDE. We draw the attention to three possible variational…
Infinite product formulae for generating functions for sequences of squares
Christian Krattenthaler, Mircea Merca, Cristian-Silviu Radu
We state and prove product formulae for several generating functions for sequences that are defined by the property that is a square, where and a…
Serendipitous discovery of a physical binary quasar at z=1.76
E. Altamura, S. Brennan, A. Leśniewska +7
Binary quasars are extremely rare objects, used to investigate clustering on very small scales at different redshifts. The cases where the two quasar components are gravitationally…
Positive solutions for a class of singular Dirichlet problems
Nikolaos S. Papageorgiou, Vicenţiu D. Rădulescu, Dušan D. Repovš
We consider a Dirichlet elliptic problem driven by the Laplacian with singular and superlinear nonlinearities. The singular term appears on the left-hand side while the superlinear…
