Positive solutions of sparse polynomial systems
Proceedings of the 45th International Symposium on Symbolic and Algebraic Computation, 2020My lecture will survey some classical and recent lower and upper bounds for the number of positive solutions of systems of n sparse polynomial systems in n variables, including basic questions that are open. This is only a short summary of the talk.

Multiple solutions of positively homogeneous equations
Nonlinear Analysis: Theory, Methods & Applications, 2002The authors study the existence and multiplicity of periodic solutions to the following system \[ u''- Au + \mu u^+ - \nu u^- = v + h(t), \] where \(h\) is a continuous and \(T\)-periodic function, \(v\in \mathbb{R}^N\), and \(A\) is a symmetric matrix. The main results are the following: (1) Under some reasonable assumptions, this system has at least \

Positive Solutions of Quasilinear Elliptic Equations
Mathematical Notes, 2005The author studies the existence of radially symmetric solutions of the problem \[ -\Delta_p \varphi = \lambda\varphi^q - | \nabla\varphi| ^s \quad\text{in}\quad B, \qquad \varphi > 0 \quad\text{in}\quad B, \qquad \varphi = 0 \quad\text{on}\quad \partial B, \tag \(*\) \] where \(\Delta_p\varphi = \text{div}(| \nabla\varphi| ^{p-2}\nabla\varphi)\), \(p ...
