The dynamic behaviour of a Lotka-Volterra system. described by a planar map. is analytically and numerically investigated. We derive analytical conditions for stability and bifurcation of the fixed points of the system and compute analytically the normal form coefficients for the codimension 1 bifurcation points (flip and Neimark-Sacker). https://macorners.shop/product-category/holographic-tote-bag/
