On spherically symmetric solutions with horizon in model with multicomponent anisotropic fluid
H. Dehnen, V. D. Ivashchuk
A family of spherically symmetric solutions in the model with m-component anisotropic fluid is considered. The metric of the solution depends on parameters q_s, s = 1,...,m, relati…

Cosmological solutions in multidimensional model with multiple exponential potential
V. D. Ivashchuk, V. N. Melnikov, A. B. Selivanov
A family of cosmological solutions with Ricci-flat spaces in the theory with several scalar fields and multiple exponential potential is obtained when coupling vectors in e…
